---------- -------------------------------------------------- -------
The 7-axis 3D printing motherboard based on STM32F401RCT6 has
a maximum input voltage of 24V, 5-way MOS driver, 4-way limit switch, supports MINI12864 screen, 7-axis stepper motor driver,
among which the XYE three-axis supports uart (no changes required) Circuit) The remaining four axes require jumpers (please see the attached manual for details).
The V1 board currently has a problem that cannot be connected when the web firmware is restarted. If anyone knows about it, you can point it out in the comment area. The V2 version will be updated after a while. , optimized the driver jumper, using jumper cap, more
convenient
