Re: [CAD_CAM_EDM_DRO] Re: Gecko Faults

That should be enough torque and way plenty of amperage to keep up with it, You probably need reduction on the drive by way of a belt. Like 2 or 3 : 1. Steppers will work without reduction because all of their torque is achieved at hold and low RPM. Servos differ in that their torque is achieved at higher RPM's. Do a "google" for "Stepper versus Servo comparison". There is a graph that will show each types torque characteristics.

Jon,
I am using gecko 320's and a 36v 25 amp power supply. I am using
Mach 2, when I jog the machine they fault, but I can go to mdi
screen and type g01 x1 f2 and they will run that way, but they also
fault out from time to time doing that. They are you 15 lb-in servos
which would be 240 oz-in. Or atleast thats what I figured it to be,
which might be my problem.
