KEYESTUDIO 3D Printer Controller Board RAMPS 1.4 REPRAP Mendel PRUSA with Stepper Jumper Screw Terminal Block for Arduino Mega and ramps 1.4 Projects
- The RAMPS1.4A is used as driving shield for 3D printers, it is easy to stack it onto the MEGA 2560 control board..
- It has total 5 slots for stepper motor drive module to drive 5-channel stepper motors. The slots are compatible with all kinds of drive modules like....
- There are 3 jumper caps under each slot, which can be used to control the working subdivision of drive modules..
- For example, if connect the A4988 and plug three jumpers, the subdivision port MS1、MS2 and MS3 of A4988 module are at active HIGH, so the A4988....
- But if unplug the three jumpers, MS1、MS2 and MS3 of A4988 module are at active LOW, so the A4988 module is in full-step working mode..
