Thanks. I did figure out a way to do it. I used a conditional (while) and that checked that status of my mid-point homing switch. If triggered, it moved 1 mm at a time in the direction towards the middle.

Following this I used a G0 command with the option (if forget what that option was called) that moves until the limit switch is triggered.

This results in the axis only moving toward center (with a little overshoot).

I am impressed with the Reprap gcode. Good job! Great flexibility!

Thanks

I am using a Duet 3 Mini+ with the latest software (3.5.4) with a pick and place machine. I don't want to move the head of the pick and place machine until the two pickup heads are in their middle position. (One head goes up when the other goes down using one z-axis stepper motor).

My hardware has a switch that transitions from closed to open at about the midpoint. This works.

I am very new to Gcode, reprap, duet, etc.

I tried using a conditional to move the z-axis in the direction toward the middle, but nothing happens. It also seems that having the z endstop triggered may cause a problem.

How do I configure my homez.g and config.g to make this work? Is is possibe?

I also noticed that homing will cause the x axis to home first, then the Y, and finally the Z. I need the z to home first, and they it is safe to move the x and y for homing.

Thanks
