[SOLVED] Duet2 Ethernet RRF3 Motor issue

@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.

Phaedrux

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.

@phaedrux

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.
Dad

EDIT:

Alrighty so I have these motors at the rating listed:
X,Y - 1.5amps each
Z,Z in series - 1amp each
E,E - 1amp each

Is 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.

Nope, you only need a single value for Z. Only E requires multiple values.
