Printing hangs in 1.5.0

cropduster · January 6

Hi there,

I tried the DEV version 1.5.0 in anticipation of my Bambulab x1c. I have two other klipper printers configured, running fine in 1.14.8. After upgrading to 1.5.0 I can still move the axis, calibrate, etc, but when I start a print, the printer hangs, repetier server hangs and can only be revived with a sudo reboot from console.

When did you test this. Will test as well to rule out a new deadlock with current version, but 1.5 is dev so it changes and can contain bugs and there werse in deed some deadlocks with new stuff I already fixed.

I downloaded the dev version on January 2. unfortunately I did not check any logfiles or console outputs by the time. The print stalled upon hitting print... I heated up, but it never actually started printing.

As I received my bambulab X1 Carbon printer, would you rather recommend the most recent nightly version?

Nightly version is 1.4.18 not 1.5.0 so will not work for x1c. Printing without ams mapping works already fine for X1C with dev, just need to check now klipper - hope it happens to me as well. Sometimes these hangs are timing dependent. Will at least test it with a few prints so I can check where it happens.

I could upgrade to 1.5.0 again and try to reproduce it. Just need to know which outputs you need to debug. I will be able to do it on Friday as I am on a business trip ;-)

I hope to get it by then, but if not what I need is a list of backtraces as described here:
https://www.repetier-server.com/knowledgebase/debugging-crashes-hangs-on-linux/

especially output from

thread apply all bt 20

this shows where server is completely hanging. Unfortunately without lines but normally I find it knowing at least the function where it happens.
