Roto Toolboard, no extruder motor motion?

Phaedrux

Can you send M98 P"config.g" and report the results here?

@Phaedrux Entering that command to the console at the web interface produces no output.

Do you experience the same issue on 3.5.4 stable release?

bug2k22

@Phaedrux I haven't run this configuration with 3.5.4. With the previous setup, upgrading to 3.5.4 broke the setup and the board firmware became corrupt and had to recover with a usb cable. So I upgraded to the latest beta on the board and sbc and all has been working well.

I presume it's not a simple task to downgrade both boards and all the sbc packages to a previous version?

@bug2k22 you should be able to run the following

M997 S2 F"stable-3.5"
M997 S2

and that should downgrade you to 3.5.4

bug2k22

@jay_s_uk Does that downgrade the boards and all sbc (pi5) packages too?

jay_s_uk

@bug2k22 yes, it should do
If it only downgrades DSF/DWC you can then issue M997 and M997 B20 to flash the firmware to the mainboard and toolboard

bug2k22

@jay_s_uk The second M997 S2 command did flash up a notice saying it was upgrading, but nothing seems to have changed, restarting the board shows the 3.6.0-beta.2 firmware on all boards and the sbc packages are still on 3.6.0-beta.2.
If I ssh in to the pi, I see that the duet3d.list is now showing "deb https://pkg.duet3d.com/ stable-3.5 armv7" so it is on the stable channel but nothing downgrades.

jay_s_uk

@bug2k22 try running M997 S2 V"3.5.4"

bug2k22

@jay_s_uk Thanks, that did complete the downgrade on all boards and the pi.

Duet 3 MB6HC 	MB6HC 	3.5.4
Duet 3 Expansion TOOL1RR
TOOL1RR 	3.5.4
Duet Software Framework 	DSF 	3.5.4
Duet Web Control 	DWC 	3.5.4

This has not changed the behaviour, still no movement on the extruder motor.
I have just double checked the cable from the toolboard to the motor and connectivity is fine on all pins.

@bug2k22 in that case i'll leave you back with @Phaedrux or @droftarts

@bug2k22 Can you try moving your M906 (set motor current) to after the M584, for both the XYZ axes and E? See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m906-set-motor-currents

Order dependency
This command must be later in config.g than any M584 command.

@droftarts Thanks Ian, it's now working!

I didn't look at M906 as it seems to work with the extruder connected directly to the 6HC even with it early in the config. Something to remember for future installs.

@bug2k22 It would have been reverting the currents to the defaults, I think. I'm not sure what the Roto default is, may be 400mA, as it usually expects a Roto extruder, which uses a lower current motor, so might just not had enough current to turn yours.
