MKS CTR module:
1.Reprap 2004LCD carries with SD card which is easy to get interference because of faster transmission rate when transfers data to main board by data line. That will inexplicably shut the machine down , or the print head run around etc .To reduce interference ,data line shielded with foil should connects to ground, while as short as possible .

2. MKS CTR can be directly connected to 2004LCD or 12864LCD, but effective SD card slot is an independent suit, so SD card slot on 2004LCD and 12864LCD is noneffective.

MKS BASE V1.4 mainboard:
MKS BASE is a feature rich all-in-one electronics solution for Reprap and other CNC devices. It features an onboard ATmega2560. Its five motor outputs are powered by A4982 stepper drivers. The board can use the same firmware as Ramps1.4. MKS Base is designed to be flexible in the user's power source availability, allowing any power supply from 12V-24V.

MKS-BASE is suitable for 3D printer manufacturers on batch production, and being used as main control board. Relative to the Ramps1.4, it adds E1 heating output.

MKS-BASE is suitable for dual-Extruder machine.

Note: Not including SD card !

Instructions for usage:
1) Can be used directly on MKS Gen,
MKS Base mainboard(V1.4 updated version ), MKS MINI mainboard.
2) If you use it on Ramps1.4, you need the L-shaped adapter board

Package included:
1 x MK base V1.4 mainboard with USB cable.
1 x MKS CTR smart controller Adapter module.
1 x 2004LCD control
1 x L-shaped adapter board.
3 x cable
