hi
i'm a newbie in EMC2 and I need help for my final project
I use two motor for Y-axis
how can I synchronize these two motor in EMC2 so they can move straight??
for your information I use
- mesa 5i20 & 7i33
- yaskawa motor for axis
thnx b4

Simple synchronization is easy, just drive the two PID loops of the slaved axis from the same source:
net emcmot.00.pos-cmd axis.0.motor-pos-cmd => pid.0.command
net emcmot.00.pos-cmd axis.1.motor-pos-cmd => pid.1.command
The tricky part is homing. I believe one of the EMC developers is currently working on gantry homing. You might ask on the EMC-users list
Wouldn't it be simpler and cheaper to use one motor and a chain/sprocket to drive the other ballscrew?

I run a mechmate. The X-gantry is driven by two steppers (and two drivers).
In the stepconf wizard, Pins 2 and 4 are both assigned to to x-step and pins 3 and 5 are both assigned to x-direction. The "invert" checkbox for pin 2 is on.
The invert function assures that the stepper attached to pins 2 and 3 are driven opposite rotation from the stepper attached to pins 4 and 5.
