Ender 3 : Upgrade to MKS Gen L v1.0 + TMC2208(Legacy) - Part2

Описание: This is the second 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 continues, where the previous left-off, with the detailed step-by-step hardware configuration and set-up. This part ends with a simple demo of the difference in noise levels from the stock mainboard versus 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.

Limitations:
1) SD Card slot unavailable on the NEW board
2) Need a mounting bracket if re-use of original mainboard casing is desired.
3) MAY need to replace 2-pin end-stop connectors with 3-pin ones as NEW board has 3-pin sockets.
4) MAY need to replace stock LCD connector as the connection is reversed at mainboard-side.
