M915 won´t accept R2 or R3

@vali3d if running 3.4RC1

The handling of driver stalls has changed. In the M915 command there is no longer a distinction between R2 and R3; both cause an event to be created when the driver stalls. To handle the event, RRF calls driver-stall.g passing the stalled local driver number in param.D and the CAN address of the board concerned in param.B. File rehome.g is no longer used. If file driver-stall.g is not found then the print is paused without running pause.g and the error is reported.

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

jay_s_uk

@vali3d are you getting any stalls at all?
Are you explicitly setting the drivers as stealthchop? i.e. D3 in M569?

vali3d

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

@vali3d did you create the /sys/driver-stall.g file with appropriate contents to do what you want when a stall is detected?

vali3d

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

@jay_s_uk The M569 looks like this:

M569 P0.0 S0                                                    
M569 P0.1 S1                                                    
M569 P0.2 S0                                                    
M569 P0.3 S1                                                    
M569 P0.4 S1                                                    
M569 P0.5 S1                                                   
M569 P2.0 S1
M569 P2.1 S1
M569 P1.2 S1
M569 P2.2 S1

@vali3d what board are you using?

vali3d

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

dc42

@vali3d is it the drivers on the MB6HC that are not invoking the driver-stall.g file, or the ones on the 3HCs?

vali3d

@dc42 all relevant drivers are on the MB6HC

vali3d

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.

@vali3d I confirm this is a bug. I will fix it in the next RC, and I will probably make a test version available before then.
