THe WiFi at the university uses a scheme with user id and password. Can i connect a duet WiFi to this type of network?

The printer is on the move to the Maker Fair. will persue at a later date.

Thanks#

the assign beeing M584 X0 Y1 Z2:4:5:6 E3
i understand that etruder is assign to 3? isnt it?
how do i unassign a drive?

Mouvement out of 3 motors remapped as per config with low acceleration, still missing the 4th motor connected to Z output of DUET wifi

Reduced the Z acceleration from 200 to 50. Now going up and down as expected.
Still no output from drive 2 Z motor...

[Update] From what i hear from theZ axis motor is that the signal frequency is too high and motors start skipping assoonas they recieve a signal . going downward is easier...

@supraguy said in Z Motor weak / one missing:

then that motor will be open circuit, since the second motor boss is in series with the first one.

Jumpers are present,and installed as per factory. could they be defective? i doubt but at this point... i'll check

thanks

This is my Driver mapping. I am controlling 4 nema 23 motors
M584 X0 Y1 Z2:4:5:6 ; Assign drivers to Z axis
X and Y are fine

• Z axis I have 3 turning and one that refuses to turn.
  I swapped motor between drive 4 and drive 2 to confirm motor is good (and it is). The drive 2 not turning.

• The 3 that are turning i can easily stop the with my hand.
  I tried increasing the current with M906 X800.00 Y800.00 Z1200 E1200:1200:1200 I30.
  no luck

Change of plan. Installed DUEX2 and connect all motors using spare drivers
