Mahor.xyz V3 pellet extruder.

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...

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!

Updated the firmware, no change in the error message.
Reduced the M566 and M203 settings, no change.

24v, have a separate supply 12V for fans and a peltier element.

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.

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.

G28 Z

• 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.

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

DUET Maestro CoreXY
DWS 2.0.4
RRF 2.04RC

I'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.

@dc42 These 2 are from the Duet3d.com

Had it turned off for a few days and no change.

That does not sound good.

Firmware Electronics: Duet Maestro 1.0
Firmware Version: 2.02(RTOS) (2018-12-24b1)
Web Interface Version: 1.22.6
Architecture: CoreXY

The problem:
Motors not receiving power

The issue started two weeks ago, had a broken stepper motor shaft printer otherwise the printer was working properly. Swapped out the motor and then got this warming of not connected motor drivers, took it apart again swapped out the cables for new cables and still had the problem.
Took off all the wiring and connected two other motors with new wires and received the same message. Somewhere along the line I realised I still had an RC version 2.02, flashed the new one on there and nothing changed.

This week I had a clog in my pellet extruder and took it apart to clean it out, after putting it back together I got the same message...

2019-01-24 17:56:04 Warning: motor phase A may be disconnected reported by driver(s) 3
2019-01-24 17:56:04 Warning: motor phase B may be disconnected reported by driver(s) 3
"

When does the problem occur?

• Fully built printer
• Only power supply connected and XY steppers
• New wiring
• New power supply

What fixed the problem the previous time?
A Deut Maestro from another printer...

What now?
Kind of at a loss how to fix this at the moment and not willing to sacrifice my last working Maestro to make this one operational...

Two weeks ago I had a shaft of a nema 17 break, so had to do some maintenance to my CoreXY.
Was finished powered the Duet Maestro on and got this message:

Warning: motor phase A may be disconnected reported by driver(s)
Warning: motor phase B may be disconnected reported by driver(s)

Gives it on all drivers.

So had to find where this problems was coming from, config? firmware?, wiring?, nothing worked...

So I have quite a few Maestro's had 3 from the fitforlauch campaign and had 2 whose U3 burnt out... still need to get the warranty on them.

Hooked up a new Maestro and it worked.

Two days ago on the same machine I had to rebuild the extruder, finished today and getting the same bloody error.

I am running 2.02(RTOS) Motor Currents, M906 X1200.00 Y1200.00 Z1200.00 E1200.00 I70;
