General Mach Discussion / All stepper motors run on their own when spindle is turned on
« on: January 31, 2013, 06:38:46 AM »
When in home position the motors try to move negative, when spindle is away from home motors move away from home!
I have stepper motors set up nicely they jog and home correctly via Mach3 when spindle is not spinning.
The spindle connects to VFD but not desktop and runs ok when only the stepper motors control box is on. When mach3 is opened up the problem starts when I get spindle rotating.
I have not touched any of the spindle settings in Mach3 and are set at default.
The cnc machine is 6040z and recommended x/y motor profile is 640 steps per, velocity 2500 mm/min, acceleration 200 mm/s/s, step pulse 5 and direct pulse 1. The z profile is 640,800,150,5,1. I am not able to set the x/y recommended profile as the velocity 2500 is off the scale and I am only able to get 2300, does this matter?
I would appreciate any help on this, thank you
