Internal error on command:"G1"

matyasf commented 4 years ago

The error in the title comes up during a print. I am on the master branch, pulled around a day ago. klippy.log

As I see from my log this is the stack trace:

The error is repeatable, it fails on the same spot for a certain .gcode file, I can send it if its useful.

There appears to be an error in the extruder scheduling. I am able to reproduce the problem from the info in the log. However, it will likely take a few days to track it down.

This should be fixed now (commit 988ee575).

Thanks. -Kevin

Same issue here. On Gcode I have been printing all week. 7 times.

I'm pushing flows on my mosquito, and from what I've seen it might be max_extrude_cross section related?
