Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Description
I have 4 filaments loaded, they are shown correctly on the printer, in orcaslicer and in the kx-bridge. When printing a multicolor print the first color that was printed (which should have been from slot 3) was actually from slot 4.
Steps to Reproduce
Expected Behavior
Printing with the right colors
Actual Behavior
Wrong color.
I tried resyncing orcaslicer, stopping and starting the print, restarting orcaslicer.

can you share gcode file please ?
and the bug is only with latest nighty ? stabel is ok ?
2 good questions, I've added the gcode, I'll try with the stable version now and let you know the results.
Stable has the same issue, I'll switch to the previous version of Orcaslicer-KX to see if that changes anything
previous version of orcaslicer-kx also produces the same result. It's getting too late for me to print today, so hopefully the gcode helps and otherwise I'll see if I can do more tests for you tomorrow. I have a very busy day tomorrow and Thursday however, so my next reply might take a bit longer
I added the 3mf file as well, maybe it sheds some more light
Amazing, thank you.
please wait .. i will test first .
No rush, I won't be able to print until tomorrow morning at the soonest
