New day, new error

[gnydick]

I was printing a multi-tool print and had to pause and re-home because I dropped a tool and when I clicked resume I got the following error message and the print was cancelled.

Error: in job file (channel File) line 0: Illegal parameter letter '8'

@gnydick Can you share the G-code file?

[gnydick]

@chrishamm Sure. It's one of these 2. I was iterating a lot, so I don't remember which one.

integrated position sensor v6 - FLEX.gcode
integrated position sensor v9 - FLEX.gcode

@gnydick What version of RRF? SBC or standalone mode?

[gnydick]

@gloomyandy 3.5.2 SBC tool distribution board, 4 tools

@gnydick I tried to reproduce this problem last week but without success. Because there is now a second report about a similar issue, could you please run the following command on your SBC (Linux terminal or via SSH) and send me the filtered log?

journalctl -u duetcontrolserver | grep -e Selected -e paused -e Illegal

It looks like DSF pauses/resumes at a bad position causing the error and the following print abort. If that is the case, the file offset from that log excerpt will prove that.

@chrishamm, here ya go

@gnydick This one was quite difficult to reproduce but we could reproduce it after all. I've got a bug fix ready which is being tested. We'll provide a bug fix for that in the next 3.5 and 3.6 versions.

@chrishamm excellent, thanks
