Beginner Introduction to Milling on a Shapeoko using Fusion 360

so i'm going to make a quick video this will be video one in a series on how to use fusion 360 for doing milling uh with a shape poco um so i'm going to show some pretty basic stuff in this video this is kind of uh an introduction to somebody who is just starting to use use fusion 360 for milling with with the shea poco so some pretty basic operations uh show how to get the machine into fusion 360 show how to create a setup and show how to create a milling operation so i'm going to start in design mode to create something pretty basic i'm going to turn on the visibility of the origin right click on the plane here and click create sketch from there i'm going to create a basic shape to mill which will be a rectangle that's a hundred by a hundred and fifty and then from the sketch i'm gonna select the profile and then extrude it and i'm going to extrude it out by 50 millimeters actually let's make that 25. once you extrude a sketch you'll have a three-dimensional object and you can start creating sketches on the surface of that so i'm going to create a couple things that i'm going to demonstrate milling with i'm going to create a circle make that 40 millimeters and it'll also create a rectangle i'm just making some basic shapes as examples i'm going to click both of those profiles and i'm going to extrude those down [Music] by negative 10 and because the end mill is round i'm going to give it a break and i'm going to round to these corners should be good all right so now i have a basic shape that i can uh mill uh so now that i'm in the mill i'm gonna go down here to manufacturer and then if you're just starting out and you have not yet added a machine you're going to need to go to manage machine library you'll see that i already have the shape hoco xxl in here and you'll see that i already have the uh post processor so fusion 360 comes with the carbide 3d post processor already included but you can go to cam.autodesk.com forward slash hsm posts uh type carbide here and get the more recent post processor uh directly from autodesk um but uh when you first uh go into this machine library you will not have any machines so what you're gonna do is click this create new and then click milling that'll bring up this dialogue um but rather than uh start from that one i'll just show you uh what those settings are and this is gonna be like you just saw the same box that pops up when you hit the plus and i'll just walk through the settings that i have um you don't have to change the lot in here you you're going to want to put the description the model the vendor these values are purely just so that you can identify that machine here in the listing so you don't need specific values here you just need something to identify as that shape of a machine now the dimensions you're going to want to get from the carbide 3d website uh for your particular machine whether it's a xxl xl or just a regular ship hip shape poco 3. under capabilities you're going to want to put milling uh you're gonna want to get some of these these settings none of these down here really need to be changed from the default uh you might want to put a maximum uh feed rate in here um but uh you know it's it's these aren't as important especially since you're going to be setting these uh in your in your tools anyways uh the work piece you're going to want to put the area that is actually millable on the shea poco so this is going to be uh smaller than the the actual work area uh that you put in the dimensions here um nothing needs to be changed under kinematics uh you can leave all of that the same nothing needs to be changed under spindle if you would like you can set the minimum maximum for spindle speed but if you leave it at 0 0 it will still allow you to set a spindle speed faster than that without any warning nothing needs to be changed for machine machining time coolant uh make sure none of these are checked uh unless uh you have some form of uh coolant uh added but that's uh pretty challenging to do on the sha poco uh uh we'll we'll talk more about that in a future video uh click here on post processing it will take a second for this to load and this is the most important part of the settings this is where you're going to select the post processor if you click on system uh you'll you'll actually find the the carbide 3d.cps under the the drop down or you could click browse uh like i did and use the downloaded one like i mentioned earlier that you can be found on this this website here so uh once you have the post processor selected you can really just say okay because uh these are left as defaults so once you've added the machine uh into the library uh you'll you'll be able to use it again and again uh you only have to add it once so the next thing that needs to be done uh and this has to be done for for each time you're you're setting up a about a series of operations um and this needs to be done if you think about setups uh if you're machining the top of something and then you're gonna machine separately the other side of it those would be done as two separate setups uh each setup is uh specific to the orientation of what you're milling uh and so i'm gonna add a initial setup and it's just one setup for the top of this because this is all that needs to be milled i'm going to say new setup here from here you're going to select that machine that you added and you're going to see that here and you can just go ahead and select that and that machine will be there you'll have million here for the sake of being able to mill things top bottom multiple sides uh and really kind of think about the orientation in the way that the shea poca works you're going to select this this second option and then that allows you uh to flip uh the z-axis if you want to mill uh the other side of an object so you would set up you would create one setup with it not flipped and then you would create another setup with it flipped for now we're just going to use it as is the next thing you want to do is select the stock point and this is an important um part of of getting this right so one of the things you're going to want to pay attention to is this up here so as you can see we're currently looking at the model from the back so we're going to want to spin that around and this is the front and so this is going to be the same orientation as your machine so when it says front here this is going to be the front of your poco top this is going to be the right so this is going to be the same orientation that your machine is in and so if you're if you want to do your zero from that front left corner you click box point and you're going to want to click that front right top corner so that's going to be the top of your stock at the very corner so you're going to zero out at that very corner uh just like you would with uh a carbide uh create um and so once you select that box point and you see that y uh is going to the back of the machine x is the x axis moving side to side and z is the router actually moving up and down you want to make sure that the orientation of those coincides with those those directions that you would expect and so remember that when you place the stock on your shapoco uh that this is towards the y is going to be going towards the back of the machine just like the the accesses are labeled uh on on your shea poco um okay so uh normally uh you know if if you only have one body it'll auto select that here if you have multiple bodies in the scene you may need to select which body that you actually want a machine here but since it only had one body in the scene uh it auto selected that body uh here under stock you're gonna see the actual dimensions of the the stock that it's expecting to mill so if you have a stock that's larger than uh the model then you're going to want to add those uh margins here so if it's if your stock is exactly the size of the model like say you have a block like this and you're cutting out of it you could say uh relative size and set 0 here if you want to add a little bit of offset on the top um just so that you're sure that the the the milling actually begins uh kind of above or right on the surface uh you can do so uh if you are like i said if the stock is bigger then the the model that you're going to mill then you're going to want to add that extra stock here and so for example if the piece that i'm milling is uh 20 millimeters larger or actually 40 since it adds it to all sides uh you can do so here and you'll see and you want to when you measure your stock you want to measure it up here you the other way to do this is to do fixed size and just put in the number uh numbers that you measured for your stock you can also do [Applause] see relative size um and then add stock to all sides and then add just the offsets for say say you have a piece and it is uh 100 millimeters depth but it is a longer board and so you're going to want to add more to just the x and so you would put like 50 here and see you can see the additional stock here say that the board was really long and you just wanted to mill the end of it you put 500 here i'm going to keep this simple and just do no additional stock at all for post process since the post processor is uh already configured uh in your machine there's nothing here that you you really need to change so now that you have a setup you have what you need to actually start adding milling operations and so uh the difference between 3d and 2d is really and people get this confused they think that because they're kind of going multiple depths uh in in the material that it might be 3d but 3d is really say the bottom of this um this this pocket was curved uh say it was like a bowl and it had a con it could like a concave shape to it that's when you would need 3d um but 2d still has the ability to step down uh or do you know depth depths of cut as it goes down so uh you know you'll see uh kind of what you are you might be familiar with the term depth of cut you'll see that as step downs and you can do that with 2d operations these are both going to be 2d operations even if this had uh this hole and then a hole inside of it that's still a series of 2d operations like i said the 3d operations are only really where there's a curve say you were trying to do uh you know what they would call like 2.5 d um where it's you know like a face that you're trying to um do uh if there was a face that you're trying to do with like a scallop or um you know like a contour kind of to carve out that three-dimensional object so we're going to do a 2d and i'm going to do two different operations here just to kind of show uh what we we can do here so um so there's there's a 2d contour and what that is is you can contour the perimeter of something or the inside perimeter or something you can use this for cutouts so if you had a you know a maybe a half inch piece of plywood or mdf and you wanted to cut a shape out of that that would be a contour [Music] so let's let's go ahead and do that so let's say um you know there was some extra stock here i could actually select this perimeter um let's go back i'm going to show you how to select a tool so every operation you're going to need to want to or you're going to need to select a tool and you can download these tool libraries um for for carbide 3d various places i'll include some links in the in the description for the video um i also have some custom tools here that has you know custom feeds and speeds for that particular tool you can find tool libraries from various manufacturers of endmills if you you know this amano one has quite a few this white side has quite a few it's they basically have uh these these tool libraries for every uh almost probably almost every uh end mill that they create so you can uh just use these very quickly and uh they're all they're already set up they often already have the right feeds and speeds uh which is really useful um but i'm going to go ahead and i'm going to go in here to the carbide 3d and use an end mill that's uh included with the shea poco that most will be familiar with which is that quarter inch 201 end mill let's select that you'll see uh here now that i've selected this tool up here that i'll have the feeds and speeds for this and what you're going to want to do is uh configure this based off of um you know your material that you're cutting so you you can find the feeds and speed uh table uh that has recommended uh feeds and speeds um for different materials um uh just if you even do a google image search for shapoco feeds and speeds you'll see a lot of those tables that show you the recommended especially for the uh the 201 end mill i already had selected that contour and that's basically gonna be the edge uh the of of any uh body uh that you can select i could select this top contour the bottom contour uh if you're gonna do a contour operation where you're cutting something out like this you're gonna wanna select the bottom contour to do so the next thing that you're going to want to configure is these is the heights [Music] and you know this this is important to be able to actually you know properly retract above your uh your stock uh generally don't need full 10 millimeters of retraction for clearance you're going to want to make sure this this top height is the top of your stock and then this bottom height is the selected contour so that's that contour along the bottom and it's going to show you those uh here visually so you can kind of get an idea and you can even just to make sure that you're you've got the proper um clearances you can you know rotate around this and get a good look um the next thing to configure is passes uh so here under passes uh you're gonna wanna um select multiple multiple depths uh it's important that you don't try to cut something out uh all in one uh go uh you're gonna wanna do some step downs and this is this step down right here is uh the same as depth of cut so if you look at the um tables that i mentioned earlier about feeds and speeds for the shea hoco it will mention doc depth of cut and so that's the number that you're going to want to get here you can leave a lot of these other settings alone the real the real one that you want to want to pay you're going to want to pay attention to is this depth of cut [Music] you don't need to change a whole lot else here over time you're going to learn kind of what you need to tweak here to get you know better better finish uh you know speed things up a little bit but the the really the the key thing here first for at least for uh doing a contour operation is to make sure you have the right uh step down uh you don't need to change a lot here um eventually you'll start tweaking uh the settings here um but uh you know the the main thing here is if you had some contours that were you know close to something else and you wanted to make sure that that lead in uh didn't cut away that the material that that that that's like from a neighboring cut and also you can tweak these settings uh to get uh you know faster machine times um you can also you know select this to keep the tool down so when it's uh going around and making each pass uh it will fully retract unless you click uh keep the tool down so i'm gonna go ahead and click that and then click ok it's going to spend a couple seconds here depending on your operation could take longer and it's going to show the percentage here if you can if you highlight this you'll actually see it building this out so these lines that you see here those are the the tool paths so it's you know much like in uh carbide create uh under simulate it'll actually show you where the tool uh is going to uh to go um it'll also show you these are the lead in operations it's doing a you know helical uh approach uh lead in um uh if you want to actually replay this um you can go here and you can go to simulate and this is going to be similar to uh you know carbide uh create where you can actually simulate it and you can press pre play here to actually replay uh and you can see the tool uh actually going through the operation um you can speed it up using this uh you can select along uh in different places in the operation here you can turn off uh the tool path just so you can just see the stock being removed but uh since since this is already the size of stock that i'm going to cut from i'm going to go ahead and remove this operation i just wanted to kind of show uh that you know outer contour operation in case you were cutting out uh the the material um i'll do a future video that shows how to use tabs because tabs are an important part of doing uh cutout operations so that the piece isn't uh you know broken loose uh while it's cutting it out you want some tabs that are left uh there to hold it in place and then you can remove those tabs with uh you know a band saw or or even a handsaw once the um the pieces is done um so the next thing i'm going to do is i'm going to show um two operations here i'm going to show a 2d pocket i'll start with that one i'm going to select the tool again um once you actually use a tool um in in you know a particular file when you go back in here it's going to have that tool already in this list which is convenient so that you don't have to go and find it in the library again so i'm going to go ahead seems to be loading here for a second i'm going to go ahead and select that tool and i'm going to select the bottom face of this so there's multiple ways to pocket but what you're going to want to do is in with most pocket 2d pockets is going to you're going to want to select the bottom face of the area that you're trying to pocket so i'm going to go ahead and select that um again uh you know you're going to want to make sure the stock top uh is you know selected here and then the the selected contours is selected here most of the time that's what it defaults to or or maybe all of the time um so you don't really need to edit that very much i often turn this to five just because uh you know i don't need it to go all the way up sometimes that saves a little bit on machine time now with this pocket operation there's going to be a new important setting here which is step over so this is this is how much uh you know as it's pocketing uh how much it overlaps the previous tool path uh and so this is gonna affect uh the finish this is gonna affect uh how much load you're gonna put on the bit uh and so you know having a step over that's too high uh with a small bit could break the bit um and i think the general rule here is uh you know half the diameter of of the the end mill that you're using um but just to be safe i'm going to put three millimeters here and then uh i'm gonna uncheck stock to leave so stock to leave is a setting that allows you to leave some material so that another operation uh using rest machining can uh just clear just that remaining material which will give a better finish but for most operations in wood on the shea poco uh especially if you get the good step over and uh and multiple depths with good uh step down you don't really need this uh second operation so you always want to make sure like i said with the contour that you click select multiple depths so it doesn't attempt to plunge the end mill down and try to do this all in one pass and then again the step down is the important setting here you want to make sure that you have a step down uh that is not going to put the end mill too far down in the material as it tries to move um uh you know it during its feed and then you know like i just set this this step over so getting these two correct is gonna give you um you know your your control of whether this is gonna be a successful operation or not um most of the other settings are really to be the fine tuning or or you know through experimentation you can learn more about them but these are the two uh critical settings here uh under linking um you know for this for pockets the keep tool down is already selected you don't really need to edit a lot of these again these are things that you can play with over time but they're not as critical initially i'm going to hit ok you're gonna see that it's building that out and so now you can see this tool path um clearing out the material in this pocket um and so uh that's that looks like a pretty good tool path now i'm going to add a second tool path for this other area i'm going to do adaptive clearing and now the the difference between adaptive clearing and say a pocket is adaptive clearing uh is designed to put uh less stress on on the tool um and so it's going to come in with the tool at uh angles that uh that are optimized to put a less load on the tool so that you'll see because i already have an operation with that other tool selected i don't need to select it again it's defaulted to that um i'm going to again select a pocket for this this time i'm going to select the bottom of this one heights again i'm going to reduce this to 5. i'm going to verify that this is the top and bottom of the stock or not the bottom of this stock at the the bottom of the selected contours um now this is this is what i'm i was talking about earlier this is optimal load so this this number uh whether it's low or high is the amount of pressure it's going to put on that end mill uh as it moves through so this is this is related to uh step over uh so uh just like it says here in the description um this can be considered the stepover amount but adaptive high speed machining will vary the step over to reduce overloading the tool so this is you know uh you could put a number that you would think of a step over like the you know half of the diameter of the end mill but this is really gonna throughout the operation uh use this number to optimize the the load on the tool so it will vary unlike step over on another operation you don't really need to change a lot of these other you can experiment with them later again i'm going to uncheck stock to leave i'm going to again make sure that i have multiple depths i do not want it trying to go uh full depth in this if this was say mdf um you know you might be able to do you know a shallow pocket or even the pocket i have here in in one go uh it's it's much safer usually to do it in multiple uh step downs uh so i have this uh at 10 millimeters i probably don't want that i'm going to go ahead and just to make sure it's a nice clean cut uh you know it's a little bit more waiting um for the machine machining to finish but it's going to be worth it for a nice uh clean um adaptive clear linking uh you don't really need again to change a whole lot here this is something that you can uh fiddle with later uh to to you know optimize your your finish are to uh make sure that you're not cutting unintentionally cutting material but for this one there really is no chance of that um or if you're just trying to fiddle with these settings to speed up the total machine time i'm gonna hit ok it's going to spend some time doing that operation and so it's hard to tell um but it it it's set this up and you'll see these tool paths that cross across here and the reason why is because it's actually always optimizing it so that when it goes against the wall to clear more it's coming in at an angle that is optimizing the load on the end mill um so the next thing you're going to need to know um to to uh to actually use this on the shape hoco is how to do the post process um so i showed you how to simulate it you're going to you know often in the beginning really want to watch those simulations to make sure that it's not doing anything funky uh it's doing what you expect um so this uh after you've done that so there's two ways to to post process off of your uh your tool pass one of those uh is to post process just one tool path so if i wanted to just do this one and then later as a separate tool path do this one or if say on my sha poco i did not have a bit setter um i wouldn't have a mechanism to measure the length of the bit between two operations that had a tool change um so i would want to uh post-process those separately but if i have a bit setter and i'm doing multiple bits or if i have both of these are the same bit um i can actually uh highlight both of them uh by shift clicking the other one or i can actually right click on the setup and do a post process from from the setup if you right click on the the tool here you can post process just the tool it's actually the same for simulate so i can simulate just one or i can click on setup and simulate both you can also get the machine time here we'll give you an estimate of how long this will take the machine but i'm going to show you how to post processes so i'm going to select both of these i'm going to click post process you don't need to change anything here uh i'm gonna click ok and then that's gonna have uh the you know the ability to save this dot nc file this is the g code and this is gonna be similar to when you export your g-code from carbide create so this is going to save out a nc file that you can load in carbide motion and run this operation and like i said uh this is post process with a uh a post processor from carbide 3d that has the ability to do those tool changes with bit bit setter so if you have a bit setter uh it will prompt you for the next tool if you had multiple tools selected here and measure that with the bit setter and continue those operations so i can save that out and run that with a carbide motion i'm not going to show that uh just because most of you probably already have experience loading and running your g-code with carbide motion um so that's that's the basics i'm going to keep it to just that for now um hopefully that was the right amount for the the first video um and in future videos i'll go into more operations uh and i'll show some uh of the more uh nuanced settings uh that you can you can do in here i also have a video that covers uh adding uh more tool libraries um and um maybe i'll all probably have a video soon after that uh that goes into some 3d operations um again though uh it's it's wise to spend some time with 2d operations a lot of things can be done too with 2d operations spend some time with 2d operations before you jump to 3d a lot of people tend to try to just immediately uh you know mill something like this with you know pocket clearing 3d operation when it's really not necessary it's it's you know really a waste of uh uh you know of machining time um and it's you know uh it's it's just not the way to to do these type of uh these type of pockets um so those are the the operations i'll show today um a new video coming soon thanks
