I’m a complete newbie to making things with CNC. So far, using a Shapeoko 3 w/ Makita RT0701C, I’ve been pretty successful with things that only require the #201 and #202 cutters, but I’m having issues with jobs that require shorter cutters.
Specifically, I’ve got a job configured in Fusion 360 that starts with using the 1/4" flat end to run a face toolpath on MDF. That works fine. I then swap out the collet for the 1/8" version I ordered from Elaire and the Carbide 3d #111 cutter (1/8" shaft, 1/16" end), but I can never get it to start at the correct surface level. Usually, it just hovers a bit above where it should be working. I usually have the second toolpath set to use rest machining from the previous toolpath.
I’m thinking the main issues I’m having are with the tool library settings and body length, but if someone has some pointers on which measurements I should be watching for, I’d appreciate it. I believe the last attempt I tried, I had the body length set to be the length of the cutter visible between the end and the nut that holds the collet in, but that left me with about a .20-.25" gap between the end and the surface during the actual cutting job.
