weird movement on every layer change
One of my Ender 3 printers does a weird movement on every layer change: It always go to a fixed position and then it resume printing and continue without problems. This problem doesn't exist printing on SD or USB printing direct from Windows machine. I've tested changing USB cable and USB port in Rpi 3b and also yesterday I've reflashed using the exact Marlin configuration all the printers but the problem continues, I can't use Repetier Server on this printer.

this thing was really a nightmare to fix (more than a month) and It's my fault
