[SOLVED] Duet2 Ethernet RRF3 Motor issue
-
Video of the behaviour?
Do you have mesh compensation active?
You can force the X and Y axis to be homed by sending G92 X100 Y100 (or whatever coordinate you like) to tell the firmware the axis is homed and at that location.

@phaedrux
heres a link to a video showing the problem.I dont believe I have mesh compensation active. I have never turned it on via the web control at least.
-
@printerdad you can send "G92 Z" so it thinks its home
-
The noise sounds like it could be binding and the motor is stalling. Does the motion move smoothly by hand when the power is off? (move it slowly)
@printerdad said in Duet2 Ethernet RRF3 Motor issue:
Each motor has its current set to 80% of its rated value.
You say that, but I don't see any motor current settings in config.g. There's no M906 command.

@phaedrux
interesting, i input all the motors' current in the config wizard but something must have happened...the motor is smooth when powered off.
-
If you send M906 in the console by itself it will report back with whatever default currents it's using. See what that is. Then change your config.g to add a M906 line to set the currents correctly and see how it behaves.

m906
Motor current (mA) - X:0, Y:0, Z:0, E:0:0, idle factor 30%hm.... currently looking up my motors' rated currents again to reenter info.
DadEDIT:
Alrighty so I have these motors at the rating listed:
X,Y - 1.5amps each
Z,Z in series - 1amp each
E,E - 1amp eachIs this the proper format for m906 assuming 85% ratings in milliamps?
M906 X1275 Y1275 Z850:850 E850:850
-
@printerdad Yes.
Duet 2 WiF/Ethernet is done in steps of 100mA and is rounded down.
-
@phaedrux ok so
M906 X1200 Y1200 Z800:800 E800:800?
Im not sure about the Z motors in series if I list it twice like I do for the 2 extruders. -

^ After finally getting a chance to input the correct current values for the motors, the binding seems to have stopped!!! Thanks guys.
