SBC Problem

@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.

it runs in normal mode, with a Raspberry4/4GB in SBC mode, it's a disaster.

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)

[Macwolf]

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.

@Macwolf said in SBC Problem:

only the speed of the Z axis is at 0.5mm/s

At what point are you seeing this speed?

[Macwolf]

@Phaedrux said in SBC Problem:

At what point are you seeing this speed?

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

Great problem solved
