Brilliant 3D Printer Accessories Set meets most needs.
Including CNC Shield V3.0, UNO R3 Board, DRV8825 StepStick Stepper Motor Module.
The 3D printer stepper motor shield V3 can be used as driver expansion board for engraving machines and 3D printers.
It has in total 4 channel slots for DRV8825 stepper motor driver modules for driving 4 channel of stepper motors. Each channel of stepper motor only needs 2 IO ports, which means 8 IO ports is sufficient to manage 3 stepper motors. This shield can make quick work for managing stepper motors in your project.
GRBL 0.9 compatible.
Uses removable DRV8825 stepper drivers.
PWM Spindle and direction pins
4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins A4 and A3)
2 x End stops for each axis (6 in total) + one Probe
Coolant enable output
DRV8825 can do up to 1/32 micro-stepping
Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
Runs on 12-36V DC.(please consider the operation voltage when powering the board.)
Please note that this is an un-assembled kit and needs soldering
Note: When inserting the A4988 module, must be careful not to insert reversely.
Stepper motor wiring as follows:
2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow), if want to change direction, can be change the position of one group, for example 2A, 2B mutually exchanged.
