Ender 3 : Upgrade to MKS Gen L v1.0 + TMC2208(Legacy) - Part1

Описание: This is the first part of the series of videos on how to replace the stock mainboard on the Ender 3 with the MKS Gen L v1.0 board together with the TMC2208 stepper driver modules operating in legacy/stand-alone mode. This part comprises of a brief introduction accompanied by a tutorial on how to configure & set-up Marlin firmware v1.1.9 for this hardware upgrade. The MKS Gen L v1.0 is based on the RAMPS 1.4 board hence the pinout & labeling are the same. The TMC2208 are high-end stepper drivers which are capable of ultra-quiet operation and detailed configuration via gcode instructions.
