[3.4.0Beta7/RC1] MZV and ZVDDD Causing Firmware Crash

KevinMar

@dc42 I put "M593 P"zvd"" at the end of my config.g and now my printer cannot be accessed via DWC

KevinMar

@kevinmar I was able to revert the config.g

attached is the problematic config.g
config - MZV problem.g

Being ran on a Duet 6HC with a Pi 4b SBC

PCR

@kevinmar hmm in the config it's upper case... Has to be lower

KevinMar

@pcr it was lowercase when I ran it lol
just made it uppercase when I rewrote it for the forum

KevinMar

@pcr also, P"type" Type of input shaping to use, not case sensitive.

@kevinmar Can you post the output from m122 if the firmware is crashing this should provide some clues as to what is happening.

KevinMar

@gloomyandy I cannot access the machine immediately after the incident, but now that I've changed the config and booted it back up, here's the output

@dc42 I have provided more detailed information above

droftarts

@kevinmar are you using an F parameter in your M593 command, for the frequency you want to cancel? Input shaping won’t work without it. See https://duet3d.dozuki.com/Wiki/M593

@droftarts May not apply here, looking at Kevin's troublesome config.g, 'M593 P"mzv" F36' is used.

dc42

@KevinMar it looks like you are using Duet Control Server 3.4b5 instead of 3.4b7. Please upgrade it via the package server.

KevinMar

@dc42 Yep! That did it!
Silly me
