I found out during printing and then researched on this and other forums. Doubble checked nearly everything which came out out.
When I push the DWC buttons or sending a gcode command it is the same behavior.
I already checked the wiring and everything looks fine to me.
I did not test with removed the Duex5, due to the fact that my bltouch is on the DUEX5.
What I can tell is that when I only use the Duet2 Wifi extruder ports, it is the same behaviour.
Hi jay_s_uk,
this concerns me as well, therefore I am asking.
As long as I use only one extruder 900 mA the torque of the Nema 17 with 44 N are fully enough.
As soon as I add another in the configuration the torque drops and I have to increase the current.

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet WiFi 1.02 or later + DueX5 FIRMWARE_DATE: 2020-05-19b2
Sorry being unprecise: DUET 2 WIFI with DUEX5 extension board.
Hi,
my Duet Wifi with Duex5 extension board should drive 4 extruder.
When I used only one Extruder the M906 command was
M906 X900 Y900 Z900 E900 I30
As soon as I added another Extruder with 900mA the Extruder0 looses torque.
With 4 Extruders working on 900mA, I even have no torque on any of the extruders.
Therefore I changed the current to nearly three times the original value,
but beeing still below 2.8 A.
Now my M906 command is :
M906 X900 Y900 Z900 E2500:2500:2500:2500 I50
Is this correct to do so, or do I miss something?
Thanks for your replies.
Dear PR10R,
the BL touch should be able to reach all corners of your bed.
Where you attach it to your carriage is more or less uninportant, because
you can add the offset parameters to your config.
When the BL-Touch is in PIN_Down mode, it needs to hit the bed
before the hotend touches the bed. My PIN_Down offset is approx. 3mm to the
lowest part of the hotend.
Hope this helps.
