Duet Maestro Z-Home moves X&Y axis.
-
DUET Maestro CoreXY
DWS 2.0.4
RRF 2.04RCI've rebuilt one of my machines that has been shutdown for ~6 months, Y & X axis are homing fine. The driver does do mention short to ground on driver 2(Z-axis), this is weird.
When homing Z axis the X&Y steppers are driven and Z axis does nothing.Z-stepper wires measurements are correct, I have three machines with the same wiring and config and not sure how to fix this.
-
I had a "short to ground" error - it turned out to be no connection on one of the wires to the stepper.
How are you determining your Z stepper wiring is correct?

Multimeter across the 2 pins that should measure ~2.6ohm.

@JohnnyBeeGood If you have only one motor wire, connected to ZA connector, check you have jumpers on ZB connector. Otherwise, post picture of your wiring, post your config.g, check for shorts on and around the Z driver, on both sides of the board. The mounting point is very close to the Z driver, so check any washer you put on isn't shorting across.

2 motor wires both, give good measurements.
-
I've checked for shorts, no shorts.
-
Mounting point is not currently in use, due to checking bottom side of the board.
-
The thing is that when I press home Z the X and Y axis move. And when I home X and Y I get the warning " short to ground on driver 2"
The config is the same as the other printer, except for the name and IP.

post your homez script
-
G28 Z
-
the G1 X Y moves the X and Y to the defined point where you probe.
so x and y movement is expected.
if the z axis does not move then that is where the problem is.
first update to 2.05.1 first.
then check the wiring of the z stepper motor.
-
Agreed XY moved is expected.
Removed the XY movement now I only need to get Z movement.Don't see how updating would fix this.
-
@JohnnyBeeGood You've got very high jerk and max speed set for Z. Could be the Z can't move, and you get a short to ground message when it tries. Try M566 Z12 and M203 Z600.

at first you posted there is no z movement.
for the firmware update. there were some fixed with the reporting in certain circumstances
-
The high jerk has not been a problem in the past (last week on the printer next to it), will try tomorrow.
Still not getting any Z-movement.
Il do the update tomorrow, to see if there is a change in reporting.
If this does not work Il pull the maestro from the printer that is now decommissioned, need to start printing enclosures.
-
what voltage are you running at?
if its 12v then that will be your problem because you are using the second z connector.
-
24v, have a separate supply 12V for fans and a peltier element.
-
Updated the firmware, no change in the error message.
Reduced the M566 and M203 settings, no change. -
try seperating the z motors anyway.
connect the second z motor to e1

Had extension cables on the Z motors, took those out (taking these cables to there limit...) and now it works.
After the 2.05.1 update my XY movement is weird(xy-homing only moves 1 motor) but ill figure it out, thanks for you guy's attention! -
post your homing script.
if you created them without selecting corexy first. they may contain h2 movements for x and y which cause that.
-
TBH I don't know what it was, changed the motor orientations a couple of times and eventually came back to what I had and it worked. Now it's printing happily on the maximum speed I can extrude ~130mm/s, 300mm/s looked really cool until the extruder couldn't keep up...

what hotend are you using?
