Protoneer updated their CNC Shield V3.0 Expansion Board, this is causing many throubles for some people.The newer boards has some changes to be fully compatible with GRBL v0.9+ versions.Up today all my boards are v3.0, so i din’t notice this until an user, who was pulling his hair, send me a wiring picture for checking. I see some differences on his board, labeled as v3.5, so mistake broken after read the Protoneer page:Since CNC shield v3.1+ boards, the PCB has been updated. One of the main news is the Z EndStop and SpnEn pins, they has been re-routed and swaped on the PCB, this mean they are now correctly labered for using with GRBL v0.9+ like 3dpBurner. So if your board version is v3.1 or higher connect the PWM wire to SpnEn pin instead to Z+ pin as on previous CNC shield v3.0 boards.
Features of CNC Shield V3.0 Expansion Board:
1.Latest CNC Shield Version 3.0
2.GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
3.4-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)
4.2 x End stops for each axis (6 in total)
5.Spindle enable and direction
6.Coolant enable
7.Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others)
8.Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
9.Compact design.
10.Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
11.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.
