Arduino CNC Shield V3.51 - GRBL v0.9 compatible - Uses Pololu Drivers

Features

• Includes Noise Filers on all endstops and the probing pin.(New in V3.51)
• GRBL 0.9 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals https://github.com/grbl/grbl)
• 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)
• Coolant enable
• Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others)(Not Included)
• Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
• Compact design.
• Stepper Motors can be connected with 4 pin molex connectors or soldered in place. .
• 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.)
