Hi,
I had just bought Maker+ and was trying some 3D reliefs with their 3D machining tool path that supports doing the finish cut with their “spiral in a box” tool path that starts in the middle and steps out a tiny bit (a hair, 0.00075 by default IIRC) on each circle. When the circle reaches about a 1/2” in size the machine makes a terrible noise and shakes. After a few circles of it doing that it settles down again and it doesn’t seem to happen for the rest of the project of about 6". I get a perfect cut when it is not making that noise. I contacted Onefinity support and they tell me it is ‘skipping steps’.
As this is just the tool path on a flat surface there is little I can change. I’ve tried changing the IPM from the original 100 down to 60, and up to 120 but that just changes how long it takes to get to the position that starts skipping. I tried doubling the stepover but that didn’t seem to help either. I don’t want to change the stepover much or I’ll lose the excellent finish.
The spiral tool path gives excellent results when it is not skipping, but when it skips I can leave gouges in the wood if it is going uphill at the time it happens since the cutter goes further X & Y than it should.
At this time I don’t know how to fix this. I could give up on the spiral cut or perhaps I can add in a special vector each time to do a raster cut for the center then a separate spiral tool path for the rest. A bit of a pain, especially given the bug I posted about earlier where I have to work around it with separate files per tool path.
Anybody with experience with this? Any suggestions?
Thanks.
