In CamBam, click on the Machining folder in the drawing tree and you should see a property called ArcCenterMode which you can change to Incremental.
In Mach3, under general config, there is a matching option called arc centers which you can set to Inc.
I hope this helps. |
Thanks for chiming in.
I'm quite familiar with the absolute vs incremental arcs in CAMBAM. But interestingly I cannot get this engraving task to show in cutviewer with either convention.
In absolute the error displays roughly as R1=73.8 and R2 = 73.27.
In incremental the error displays roughly as R1=0 and R2 = 0.56.
Here are the first few lines of code, can someone else try it and see what they get?
