How to. 2 or more motors on one axis. Gantry

the Z limit woudt be the one needed most
sa it is for Toolmesure workpice mesure against the Mashine coordinate system
youshoudt realy have there one

I'm having issues with the homing and travel of the gantry. I have both motors mounted on the backside of the CNC, and 2 home switches on the back as well. If I free pull the gantry to the back, the switches are pretty close to closing and opening at the same time. I can get both steppers to travel but once the switches are engaged, Y1 stepper wishes to keep traveling in the same direction. Once the homing is done (I don't have the gantry connected), and I have the X Y Z on the program, if I try to jog the gantry, Y2 stepper goes the right way either on the + or the -, but Y1 only goes one way. Any suggestions?

Make sure you don't have the step and dir signal wires crossed going to the Y1 drive. A stepper drive with the step signal connected to the dir pin, will often behave this way.

I had an extra digit in the hal config y1ldir instead of y1dir

Hmmm, strange things happening to my setup:

My goal is to move the gantry (not just one motor) jogging, and I currently only have two motors connected (y1 & y2) of the four.

When I activate the Manual Control and select the axis in the GUI and use the - / + buttons:

• X does nothing as expected (not connected)
• Y only moves the motor connected to pin 56, would be nice if it would move the whole gantry instead
• Z does nothing, as expected (not connected)

When I activate the Manual Control and use keyboard keys:

• left/right do nothing as expected (X, not connected)
• up/down only moves the motor connected to pin 56, would be nice if it would move the whole gantry instead
• pg up/pg down moves the motor connected to pin 89 (:S ???)

I've tried but that gives me the option to control individual joints, and I would like to move two motors with one command...
Any suggestions?

Have you homed all the axes before trying manual control? Strange things happen until after homing is complete but I don't know why!
