In general you wanna choose the top of your material as the home point. We pick a spot that makes sense for the model like the middle of the piece or a corner. For Carvey that is the top of your material in the bottom left corner.īut for a lot of other machines like the X-Carve you can set your home point almost anywhere. Some machines auto home to a certain point, so you should set your origin to that location. The origin shows your machine what it should consider to be zero, aka it’s starting or home point. Then choose the origin from your stock box point, or model box point. To orient your model correctly, click the top of the stock for the Z axis… On the window that pops up, you can easily change your work coordinate system. If your model is not oriented correctly, right click your setup on the left menu and click edit. Lastly, this wasn't a sponsored project or anything, but we'll go ahead and link to Fusion and the CNCs we used in this video:Ĭarvey: X-Carve: Fusion 360: Easel post processor.

First, a link to the Fusion 360 3D file we're using so you can follow along/poke around: So we've put together this beginners guide to using Fusion 360 CAM for your CNC.īefore we dive in, here are a couple things to help you follow along. I couldn't figure out where to enter the flute value.Fusion 360 is an awesome tool you can use with your CNC because you can do fancy cuts like 3D curves, slopes, and complex layers. Here is how I configured the tool. Does this look correct given the specs of the tool at the URL above? The definition says 1/8" shaft and 0.07" flute and 0.12" cut diameter. These are the thread milling operation settings: I haven't run this yet on the machine, I'd like to double check first because this tool is expensive. Now the simulation looks reasonable (after setting the "Lead to center" option, without which the tool seemed to crash into the stock). The help says that this should be the thread depth or difference between major and minor diameters, so I changed it to 0.7112mm ( 4.1656mm OD for #8 minus 3.4544mm tap drill size). ![]() I then saw the "Pitch Diameter Offset" value which was set to 0. This is how that looks in the simulation: But the thread milling operation just lowers the tool into and raises it out of the hole in a spiral motion without cutting, it seems to just touch the walls of the hole with the edge of the cutter. The diameter of that (about 3.4mm) seems correct according to Wikipedia's tap drill size list. What I get when I run this, both in the simulation as well as on the machine, is just a hole from the bore operation. I set this up in CAM as a bore followed by a thread milling operation. ![]() I configured a custom thread milling tool, more on that below. I first created a hole and then applied the thread tool to that with these settings: I'm trying to cut #8/32 threads with this thread mill:
