Plug your 4-pin NEMA 17 or NEMA 23 motors into the corresponding X, Y, and Z headers. If a motor spins backward, you can flip the plug 180 degrees. 4. Limit Switches
The is a specialized breakout board designed to work in tandem with an MKS mainboard (like the MKS Robin, MKS Gen L, or MKS Eagle). Its primary function is to control two independent laser modules OR a dual-filament hotend (e.g., a Chimera or Cyclops).
Miswiring EXP1 to EXP2 will short the 5V rail. Always match the red line on your ribbon cable to Pin 1. Makerbase Mks Dlc V2.1 Manual
The V2.1 has two critical jumper blocks. Do not ignore these.
