SBC Problem

[Macwolf]

I have a tool changer (E3D self-made) boards Duet 3 6XD, 3HC and toolboards.
it runs in normal mode, with a Raspberry4/4GB in SBC mode, it's a disaster. when I press Home All, coupler, 15s delay,Y, 30s delay. and Z is not moved at all.

the 6XD controls 5 JMC-CloseLoop X,Y and 3xZ

does anyone have any ideas thanks

@Macwolf maybe provide more details? Start with your config.g, homing files and M122 outputs for each board

[Macwolf]

homez.g homey.g homex.g homec.g homeall.g config.g
M122 Report.txt
the machine is running in stand alone mode, but there is this delay in connection with the SBC.

M122 in SBC or Stand olone?

[jay_s_uk]

@Macwolf m122 from the 3HC and toolboards. Send M122 BX where X is the CAN address of the board

[Macwolf]

X, Y and 3xZ are all on the motherboard

@Macwolf it should be M122 B23, not M122 P23. And so on.

Do you mean that it runs OK in standalone mode, but doesn't run properly in SBC mode? If that's what you mean, are you certain that the config.g and homing files you are using on the SD card in the SBC are identical to the ones you used on the SD card in the Duet when you ran in standalone mode?

Yes the files are idendical

the config is of course a bit different (lan settings)

with the 3.5beta 1 the SBC mode works.
Z moves, but there are still bugs.
I'm looking forward to the 3.5 final
the bug is

@Macwolf I'm not certain this is the problem, however M92 takes only a single Z parameter even if you have multiple Z drivers.

what do you mean by a parameter? a small example?

M92 Z640 ; only ?

correct

[Macwolf]

the error message is gone, only the speed of the Z axis is at 0.5mm/s is that due to the beta status?

You should remove the multiple values for the Z axis in all of these commands. It is set per axis. The only time multiple values are required is for extruders as they are independent axis.

At what point are you seeing this speed?

[Macwolf]

@Phaedrux said in SBC Problem:

when homing above at "requested speed"
and of course the bed that moves in slow motion. Z also moves at 0.5mm/s when moving
