General Mach Discussion / AXYZ Retro Fit - CNC stop/start at 90 degree increments
« on: September 10, 2021, 11:47:29 PM »
I have been messing around with this upgrade for a few years now. I Have AXYZ 4008 that I updated to a Mach3 control system. All the axis work and move smoothly and I can start and stop the spindle. So the basics seem to be good. My problem is when I actually cut a job the machine does not run as smooth as it should. For example it I do a profile cut of a circle it come out correct however when I do a pocket cut it will leave a "dent" at the start and stop point. the remainder of the circle is ok. While cutting the circle the machine will stop at ever 90 degree point. Also if I do a pocket of a square the machine will leave "dent" at every direction change (at each corner). I have changed CV settings and tried exact stop settings and nothing seems to make a difference. I have looked at lots of videos of other Mach3 controlled machines and they don't seems to stop at the 90 degree mark on any movement.
I use VCarve Pro for the cad/cam and use the Mach2/3 arcs inch post processor. I am using a smooth stepper network adaptor to a break out board.
Should I upgrade to another more robust Mach3 controller?
