General Mach Discussion / Re: SERVO MOTOR RUNNING NOT SMOOTHLY

« on: October 19, 2007, 07:55:04 PM »

Well, that is what we are testing right now (drive swapping).  I'll give you some news.  By the way, what can be wrong in the tuning parameters?  I put around the same acceleration slopes than the other axis.  The potentiometers of the gecko are exactly at the same position.  I've no clue of other critical parameters.

Thanks,

General Mach Discussion / SERVO MOTOR RUNNING NOT SMOOTHLY

« on: October 18, 2007, 06:58:23 PM »

Hi, I have a set of Gecko drives connected to 3 servo motors and one motor is not running smoothly... It is moving with small steps of a few touths yielding very rough surfaces.  I just don't know why because other motors are just fine...  It doesn't seem to be a mechanical issue because it remains the same in an unloaded state. It happens on every G code moves and during jogging.

Please help me someone.
Boubou.

General Mach Discussion / SERVO ACTIVATION USING MACH AND GECKO DRIVE

« on: October 12, 2007, 02:58:26 PM »

I've made a complete retrofit and here is the only problem:

SETUP
Servo + Gecko drive + Mach

PROBLEM
How to tell Mach that the gecko board are in control or not in control of the servo.  Every times the motors are desactivated (overtorque, etc.) by the gecko board the mach controller continues to send pulse and doesn't fall in estop mode forcing us to start again the whole program and take the zeros again...very annoying.  Can I use something to tell the software that the gecko board is not activated?

Thanks,
