General Mach Discussion / Re: z axis moving up
« on: June 29, 2012, 12:04:45 PM »Hi Rich
We finally got it solved. That 20" dia. circle really shows up the errors The following settings have stopped the errors. Only the Z axis had power to the stepper during the testing. I am sending pictures of the pointer and scale used to determine the errors.
kernel 25000 hz
pulses/inch=25601 for Z axis
vel.= 20"/min., accel.= 2, step and dir.= 1 Us
set computer to "standard pc"
turned on the Sherline 1/2 pulse
I ran a 1" test up and back to zero 20 times with out any visible error.
We than cut a 5" diameter buffalo nickle very nicely in MDF.
Thanks to everyone for your help and suggestions, and especially you Rich, Mach 3 is an exellent program and at a very reasonable price.
