In order to reduce the high temperature caused by high current on Mega Controller board, it is suggested to add 12V heat dissipation fan. Hot bed part supports 11A current, 12V, other parts of the circuit, 5A, 12V. Power supply part:power input is 12V-35V, dual power supply design, effectively avoiding mutual influence. PWM DC output (heating tube, fan, etc.):6 output (1 high current, 3 medium current, 2 low current) are driven by high performance low conduction resistance MOS transistors, each output is indicated by LED.
Support 6 A4988 DRV8825 TMC2208 TMC2130 TMC2100 and other driving boards. With LCD extension interface, it can connect SD extension version of Chinese LCD screen to realize offline printing (support 204).Įxtended interface of steering gear to add automatic leveling function conveniently.
