Duet 3 6HC + 6HC as expansion: Extruder motors not working
-
Hi,
I'm trying to run a 6HC v1.01 mainboard + 6HC v1.0 as expansion to accomodate 4 extruders on my Jubilee toolchanger, but I'm having trouble getting the extruder motors to work.
Until yesterday I had a working system with the 6HC v1.01 + 3HC v1.02a, with three tools all running on the 3HC board.
I changed the 3HC for a 6HC v1.0. All changes were made to enable the 6HC to run as an expansion board: congif.g for the expansion board with only the M954 command, both boards running RFF 3.5.4, and congif.g for the 6HC v1.01 mainboard was changed to accomodate for the changed adresses for the fans. M122 report look fine:6HC v1.01 mainboard:

None of the extruder motors respond to any extrusion command when the appropriate tool is selected & hot.Checked fans, themistors & heaters: working properly.
Checked extruder motors and drivers on the 6HC v1.0 board: working properly when configured as a axis instead of an extruder.
Then I started to check in the config.g file to see if I missed anyhting in configuring the tools....And that's where I'm stuck.
Can someone please take a look at my config.g to see if I'm doing anything wrong?

@Maurits it’s a bug, has been reported and fixed in 3.6 betas, but has not been back ported to 3.5. See https://github.com/Duet3D/RepRapFirmware/issues/1058
Use 3.6-beta.2 https://github.com/Duet3D/RepRapFirmware/releases/tag/3.6.0-beta.2Ian

@Maurits also add a G4 S2 command early in config.g to make sure the expansion 6HC is ready to accept CAN commands when the M584 E command is executed.

@droftarts Thank you for pointing in the right direction. Just updated firmware on both boards to 3.6.0beta2 and all extruders divers are working fine again.
Again thank you for your help!

@dc42 Thanks for the tip! I'll definitly include the S4 command.
