Hi,

I have checked the M122 B1/2 comand. The firmeware update I installed in September, didn´t install the firmeware to the expansions, only to the mainboard. Now I manualy installed the 3.2beta to expansions (with the M997 B1/2) an the mainboard. I keep you updated.

I don´t think that there is a Problem with the file. The Problem is that the R3 cant be set. When I do M915 X S3 R3 and then M915 the configuration of the axis is on the default settig.

@dc42 all relevant drivers are on the MB6HC

@jay_s_uk MB6HC+2x EXP3HC (see https://forum.duet3d.com/topic/18329/duet-3-expansion-looses-connection)

@jay_s_uk The M569 looks like this:

M569 P0.0 S0

@dc42 I now created that file with some contents. Sadly that did not solve the Problem.

@jay_s_uk when I set a R1 it log them in the console

@jay_s_uk I should be able to set both modes, when testet it does not detect the crash at R2/3.

Hello,

I have problems getting the crash detection to work again. Since upgrading to any of the 3.4 versions the crash detection won´t trigger (see https://forum.duet3d.com/topic/26051/3-4-0-beta6-crash-detection-problems). Recently I noticed that the M915 command does not accept an R2 or R3, which might be the cause of the problems. The configuration with R1 works fine and log the crashes.

But any configuration with R2 or R3 results in the defult state.

Any idea what might be wrong?

@dc42 it didn´t fix the rehoming, but I found somting interesting. I experimeted with the R parameter an it does won´t accept R2 or R3. This is the firmeware you gave me.

When it is configured to R1 log, it does log a crash.
On 3.3 I can configure it to rehome.

@t3p3tony nothing working . I switched between log and pause, no response/pause. Then I configured one axis by M915 X R0 F0 and M574 X2 S3 to home by stall detecion, the motor stalled but ist was not detectet.
