Hi everyone, Due to a failure of the motherboard of my Anet A8, I decided to upgrade it by installing the following kit : - Arduino 2560 R3 - RAMPS 1.6 PLUS - TMC2130 drivers on X,Y,Z and E - Installed the new marlin 2.0.5 with Arduino 1.9.0 beta (because 1.8.12 is always making compiling errors). Please note that the issue I'm about to decribe was the same with marlin 1.1.8, 1.1.9 and bugfix 1by bretonesf - Firmware - Marlin
