[bug] Layer Shifts on final 1.1.9

[Anycubic]

Description

I have a Delta printer. After upgrading from 1.1.0 to 1.1.9 I have layer shifts on pretty always same heights on both x and y axis. Reducing speed, acc and jerk, raising vref does not show any improvement. I also got this tested with same printer with magnetic effector and fisheye bearing and I have exactly same issue. 1.1.5 have same issue.

Steps to Reproduce

1. Turn on printer
2. Print 3Dbenchy with "M420 S1" in the GCODE

If I print same object without "M420 S1" (so leveling disabled) everything is fine

Expected behavior: Flawless print

Actual behavior: Level shifts at always same heights

1.1.x is end-of-life and will not be receiving any more updates. Please test with bugfix-2.0.x and see if the issue is still present in that version of the firmware.

Thank you

@Anycubic problem solved?

@boelle since then I switched to TMC2130 and still had the issue on 2.x. A few days ago I also changed the board with a Re-arm (hoping that more powerful CPU will sort skippings out), so need to test everything again

[boelle]

@Anycubic did you re-test?

[Anycubic]

Sorry but lately I'm very busy with my job, hope to have time to re-test in the next few days

@Anycubic maybe click close below and open new issue if problem is still there?

[Anycubic]

Ok, done
