3.5.0-RC1: Major Issue with Skipped Steps
-
After flashing RC1 on my Maestro and trying a few simple test prints, I did my first actual print last night and it didn't go well. This is a print file I have used many times before.
I heard some strange noises and went to check on the print. Here is what I saw:
I flashed back to B4, made no other changes, and got the successful print behind.

@CCS86 Are you running input shaping? If so try disabling it and see if that makes any difference. Also capturing and posting the output from M122 after a failed print might provide some more information.

Yes, I am running IS.
I'm not sure when I will get a chance to test again, as I run pretty steady production on this machine.
