General Mach Discussion / Does Mach calculate accel/velocity rates for G53 any different than G00
« on: January 09, 2009, 01:27:49 PM »
Does Mach calculate accel and velocity rates for a G53 Absolute machine coordinate move any differently than it does for G00 move in the programs?
I can set the velocity to 1600 in per min and the accel to 35 in per min on my EZ Router Scorpion table and it will run G00 moves smoothly all day long, but as soon as it runs a G53 move it will respond very jerky and usually faults one of the axis servo motors. I have had to compensate by reducing the velocity to 1000 and the accel to 20 in per min but it is still always jerky with a G53 and smooth with a G00. Does anyone have any ideas what I need to do to correct this?
