Features: All the functions set on a board to solve the problems that Ramps 1.4 is troublesome and has cumbersome combination interface. 2560 and ramps1.4 set on a board, to solve the Ramps1.4 combination interface cumbersome and prone to failure. Using high quality MOSFET tube, the heat dissipation effect is better. Accept 24V input, the hotbed current can be reduced to 1/4 with the same system capacity, it solves the heating problem of hot bed MOS tube. Users can change their own motor drive, support 4988 drive and 8825 drive, TMC2100 drive. Reserve external drive signal, can be connected with large drive to drive 57 and 86 motors. The use of dedicated power chip, support 12V-24V power input, to solve the Ramps voltage conversion chip fever, power supply problems. Description: Stable and reliable filter circuit, greatly reduce the possibility of interference, the greatest possible to avoid the printing process, such as crashes, running around and so on. The use of CH340 serial chip, in ensuring the stability and reliability of the premise, reduce costs, but also to solve the past 16U2 difficult to install drive problems. The use of open source firmware Marlin, configuration and ramps1.4 exactly the same, can directly replace Ramps1.4. It can be directly connected to the 2004LCD display and 12864LCD display, can support the development of customers TFT28, TFT32 touch screen. XYZ shafts adopt different colors of terminals to correspond to the motor and limit switch, so that the wiring is convenient. User-friendly design, with different colors of the terminal to distinguish the driving direction, reduce the probability of interpolation, prevent driving plug but damage the motherboard. Specification: Model: Gen-L V1.0 Board color: black Size: 110*84*20mm/4.33*3.31*0.79 inch High current solution: 4.5A big motor drive: MKS TB6600 Drive Diffuser: MKS CD Package included: 1 x 3D Printer Motherboard
