1. It gather all function on one board, which solved the Ramps1.4 combination interface problem that easily out of order
2. Using 4982 as a motor drive, the SOP package, the effect of heat dispelling is better circuit board uses the high quality of 4 layer board.
3. Optimize heat dissipation and Ramp Is 2 layer board.
4. Using special power supply chip, support the 12v-24v power input to solve the problem of Ramps voltage conversion of chip fever.
5. Accept 24V input. Under the same system power can reduce the current hot bed to 1/4, effectively solve the problem of hot bed MOS tube heating.
6. The firmware can use open source firmware Marlin, configuration are exactly the same with ramps1.4 , can be directly replace ramps1.4 also can be connected directly to Ramps1.4, 2004 LCD control board and the LCD board (12864)
1. Before connect power supply, please confirm whether the connect of positive and negative are right.
2. When connect the power, do not plug motor drive for easily leading to burn. Also do not adjust the current in the motor is running.
