Description

Features:

GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13)
2 x End stops for each axis (each axis pair shared by same IO pin)
Spindle enable and direct connection.
Coolant enables connection.
Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825, and others) see our module HCMODU0068
Jumpers headers to set the Micro-Stepping for the stepper drivers.
Compact design.
Stepper Motors can be connected with 4 pin dupont/molex connectors.
Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
