First layer Ok second one shifted

General Discussion

Some comments:

  • What is the reason to use baud = 230400. The default should work fine and is the most stable one
  • Your run_current settings seem exceptionally low (this could potentially lead to layer shifts). See Hold_current and run_current -- TMC2209 - #5 by Sineos for some more information
  • square_corner_velocity should be left default 5 unless you have good reason to change

Apart from too low current = low torque, such shifts are often the result of binding axes or similar mechanical issues.
