Duet ethernet running latest firmware motors not moving at all

6.6 ohms and 6.5ohms 1.8 degrees motor
I dont have the specs because they're came with the prusa MK2 printer.
The 1.2A is just a random number. It was oringinally 800mA when it was running on the duet wifi.
this didn't work on the duet ethernet so I increased it to 1.2A.However I am confused it definately was working with the duet wifi because that's how I printed a base mount plate for the duet wifi. It was also working on the original board which is 12v.

Warning: motor phase A may be disconnected reported by driver(s) 0
Warning: motor phase B may be disconnected reported by driver(s) 0that means both phases are not connected to the stepper drivers.
do you get this on all of the drivers?
-
I still suspect a bad connection at the plug.

@Veti
I do when I home all axisI did try another motor from a different printer and it still didn't move

even on the extruder driver?
-
@Veti
I didn't try.
I don't have any filament loaded. Is there a way I turn off the temperature limit? -

Yes there is. https://duet3d.dozuki.com/Wiki/Gcode#Section_M302_Allow_cold_extrudes
-
yes even on the extruder
Warning: motor phase A may be disconnected reported by driver(s) 3 Warning: motor phase B may be disconnected reported by driver(s) 3
Is it that likely all of the drivers are dead?
Is there a common component that controls all the drivers?
-
JUst tried remapping x axis to e1 motor driver for the hell of it and I get the same error.
So I get this warning for all 4 stepper drivers
-
It is incredibly unlikely that all the drivers are alive enough to respond to SPI commands that report disconnected coils, and dead at the coil driver.
It is time to cut those connectors off and properly crimp on the connectors supplied with the Duet.
-
So I have desoldered one of the connectors off the original board then soldered a fly lead to it.
The connector on the end I plug into the board is the standard white jst ones you get on motor/ lipo from china.I connected it to my bench supply with 24v running through it. IT still the same.
I was able to use my multimeter to prove there is a continuous loop from the driver to motor and back again on both windings.So I can't see why it's not working
-
Have you checked the 7.5A fuse? It's the one closest to the Z stepper. Remove, visually inspect or use a meter to check continuity, and reseat if okay. This provides protection for the steppers and heaters, so check if those aren't working either.

yes the fuse fine.. The very first thing I checked.

G31 P500 X230 Y9 Z2.5 ; set Z probe trigger value, offset and trigger height
your x offset is bigger than the probing area. it cant be 23cm away. i dont know what this would do.
M92 X80.00 Y80.00 Z4000.00 E420.00 ; set steps per mm
your z steps seem way off. it should be 400.
please check if there is continuity between the trinamic chip output and the pins.
https://www.trinamic.com/fileadmin/assets/Products/ICs_Documents/TMC2660_datasheet.pdf
using OA1, OA2 and OB1, OB2 pins.also are you sure its a genuine board and not a chinese clone? if its a chinese clone they could have used bad chips.
-
Thats what I mean't by tested from the driver to motor and back again. Definately genuine from ooznest

M201 X500.00 Y20.00 Z250.00 E250.00 ; set accelerations (mm/s^2)also your y acceleration is way to low and your max speed way to high

Low acceleration is OK, but the unreasonably high speeds in M203 could be the problem. Try reducing them from 360000 to 6000.

Thanks alot david.
As soon as I used the values hard coded into prusa original firmware it started moving.
Good damn it always a pebkac
