Stepper motors only move when homing

Check if your endstops are making a connection to the board. The problem you are talking about happen to me or it was similar. There should be a red led light beside each stepper motor connection to the board lighting up if your endstops are connected correctly. I believe depending on normally open and normally closed endstops what I said may be reversed.. Just click your end stops and see if the LED lights I was referring to turn on and off.

After you home the printer, does the homing button colour in DWC or PanelDue change from orange to blue, indicating that homing was successful?

@mydayofplay I tried with and w/o endstops connected. No difference

@dc42 It does not change colour and I don't allow it to continue moving for more than 3 seconds because of noise. Shouldn't ever sound like that

I suspect the steppers are miswired, the most reliable method is with a voltmeter, or checking the wiring diagram from the stepper motor manufacturer.

This is especially true if multiple motors are exhibiting the same behavior.

You have this in config.g:

M574 X2 Y2 Z2 S1 ; Define active high microswitches

You have defined the microswitches to be active high and at the maximum end of each axis. Are they really all at the maximum end?

@elmoret I will try using a multimeter to determine the pairs again.

@dc42 The endstops are at the very top of the delta printer. They are also normally closed with the light ON indicating they're not triggered. The endstop light next to the motor driver is also lit.

I'm sorry, I should have seen from your earlier post that it is a delta.

The firmware will not allow regular movements to be made on a delta before all the towers have been homed. As you are not allowing the carriages to home, the firmware is behaving correctly.

My suggestions:

change I0 to I1 in your M350 command to enable interpolation. This will make it quieter.
reduce the motor currents in the M906 command until you have it working properly. What is the rated current of your motors?
test the 3 tower motors individually using G1 S2 moves as described here https://www.duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Delta_printer#Testing_the_motors_individually
the homing speed you are using may be exciting a resonance in your printer mechanics. Can you see or feel the belts vibrating outwards?
if the motors vibrate very noisily but don't actually move the carriages, that indicates that the phases are not paired.

Turns out the B+ and B- needed to switch places! Thank you all for your help but the x-axis driver seems to be dead as the Y and Z axis motors are moving..

Ya3ny

Is it possible to use the E1 driver for the x-axis just to get by until I get a replacement?

dc42

Yes, you need to include M584 X4 E3 in your config.g file, before any M350 or M906 commands.
