I run a Makerspace and am a long time mentor for FRC1296. A maker joined who is a parent of students from another team. I just bought a OMIO X8 and other makers are using it for wood with no problems.
I’m trying to get a part cut (to show them how to do it themselves) - happy to do it. It looks good but the Z is screwy. It is 0.250 polycarb and the students have the depth of cut at 0.290. Z0 is set on the face of the part I think. But it is not cutting all the way through, not even close only 0.150 deep or so.
I’m trying a 3/16 2-flute mill with 8000RPM and 20 feed rate. I’m looking for things to try. Any wise mentors or students out there who can help a guy/team?
My spoil board is kinda rough, simple plywood. I think I should cut some MDF that would be way flatter. But the part perimeter is pretty uniformly cut shallow. I doubt the spoil board is so untrue it is the problem.
The bit is pretty tight. I doubt it is slipping
Are my feed rates and plunging rates too high? Maybe I’m losing steps in X because it is too difficult? But it seems to cut like butter as one would expect.
I do not know Fusion360 very well. Are there some magic offsets that could be doing this?
