GRBL CNC Shield + Nema23 Stepper Motor + TB6600

Custom made GRBL CNC Shield + Nema 23 Stepper Motor + TB6600

Hello friends in this post I have made a custom PCB for the GRBL CNC Shield + Nema 23 Stepper Motor + TB6600.

So you’ll tell what is new in that right ? so the new thing is that this CNC GRBL shield used to control NEMA23 stepper motor.

In current situation we have GRBL CNC SHIELD V3 which can only control NEMA 17 stepper motor with A4988 stepper driver.

What if we need to install NEMA23 Stepper motor in CNC machine for more power.

you cannot do this task with traditional GRBL CNC Shield. either you have to shift for MACH controller board which runs on proprietary software MACH3/4.

In this case you have to invest a lot in hardware and software, and for the sake of hobby CNC MACH way to complicated.

But after using my CNC Shield you can easily connect 4 bigger stepper motor and TB6600 Stepper driver very easily and enjoy your CNC work on GRBL version without any issue and this CNC shield works on Arduino Nano so your control box even get compact.

You can all components which latest version of GRBL supports like

  1. Coolant
  2. Resume
  3. Hold
  4. Abort
  5. Spindle direction
  6. Spindle Enable
  7. E-stop
  8. X-Limit switch
  9. Y-limit Switch
  10. Z-limit Switch
  11. Enable
  12. X_Step
  13. X_Dir
  14. Y_Step
  15. Y_DIR
  16. Z_Step
  17. Z_Dir
  18. A_Step
  19. A_Dir

A-step and A-direction is for to mirror any other 4 Axis.

In order to enable this 4rth Axis you need to add jumper at shown location.

In fact you can connect any bigger stepper and most of any Stepper driver will work with this shield.

It is compatible with stepper driver like

  1. TB6600
  2. DM556
  3. DM542
  4. TB6560
