Acceleration that works fine for 2D work may be too high for 3D and V Carving.
Reduce your acceleration by 50%, and see if it fixes the issue.
Hi everybody, I'm writing with the hope somebody would have encountered the same problem then me...
I'm using rhinocam with mach3.
My machine i correctly setup, motor tuning and acceleration is fine.
If I try to run a simple square in 2D with defined dimension it works perfectly.
Problem starts when I'm doing V-carving with a 45° V bit.
Even thought the G-code seems to be correct and the preview in the cam software is exact the cut is different.
I seems that I'm loosing steps at the end of my code ruining my piece of work
In the attached images you can better see what's my problem.
We can clearly see what's happening at the upper right corner that stays rounded. The V bit exit to early...

Hopefully somebody had the same problem previously and could help me to figure out.

Thanks a lot for replying i'm gonna try that now
THX great advice, I tried few times by decreasing the acceleration and it worked perfectly, I had to go down from 400 to 50.
Hello everyone, sorry for my English.
I'm new to the forum and I'm looking for a solution to a similar problem with rhinocam and mach3.
I have problems with the rhinocam postprocessor to mach3 and I can not use the machine.
I am testing a rhino trial version so I can not consult MecSoft.
Lucas, have you been able to solve your problem?
I would appreciate your help, thank you very much.
Best regards.
