General Mach Discussion / Re: Tangential control bit - buggy behavior?

« on: January 22, 2009, 11:38:01 PM »

I just went back to a legacy copy of Mach 3; no more issues with it cancelling my feedrates wen doing circular pockets. It's worth a try.
Also, the shuttering seems like an independent issue. Could be motor tuning or speed of feedrate vs cutting rpm?
Changed the dir and step values as high as possible in motor tuning as per someone elses post because large arcs (9' radius etc.) sounded like a dying cow. Movement is a little smoother but I am still missing steps occasionally. Maybe a higher kernal speed above 25mghz if my CPU will handle it?


Good Luck

I'm trying to solve G1 resetting my feed rate on arcs in a new version of mach 3. I was reading through the user guide and stumbled across a section regarding the tang feature for cutting. It said it won't carry through more than one line of code for multiple arcs. You have to manually program the arc with a series of small G1 moves.

You say it is keeping the setting just not executing it. Why not try cancelling the setting after the 1st arc and calling it out again after the G1 you execute.

I'm kinda new at this ....just a thought.
