General Mach Discussion / Problem with motor tuning
« on: August 30, 2011, 02:56:43 AM »
Hi,

Hoping the forum can help with a problem.
I am configuring my machine at present and am having issues with motor control.
I have great success tuning my motors under the tuning dialog box, got steps per mm correct etc. get good smooth running accel on all axis.
But when I save and exit the motor tuning dialog box, the motors do not perform the same at all.
When trying to jog or run code they act all jerky/stall move roughly etc.

If I slow the motors right down under the tuning dialog, then save exit. The machine settles down a bit, but still runs rough in comparison to the setting in the tuning dialog.

Any suggestions.

Oriental motors 7.2 gearbox
gecko 203's
running 56v
mach3

have checked all wiring

mach 3 pulse test all good.

Any help much appreciated. Been trying to resolve this for days.

Andrew
