General Mach Discussion / Re: Motors are buzzing???Help
« on: September 20, 2010, 04:43:49 AM »
I have reduced the current and speed (approx 100 rpm) all motors run at lower speed continuously in either direction without stopping
As soon as I increase the speed the problem of erratic stopping returns, its like the motors are loosing the signal to run
Acceleration may be to high, its a juggling act with steppers to find the sweet spot. May also need a wider pulse, depends on make of drives and sometimes the computer but try setting Pulse Width and Dir prechange to 5.
