This shield used to run heavy stepper motors like nema23 on grbl & arduino nano as microcontroller. It is compatible with stepper driver like TB6600 DM556 DM542 TB6560 GRBL CNC Shield PCB file, Schematic, Connection diagram details. 💻visit for more projects :- 👉 👉 👉 FB page :- This video is made for entertainment purposes only.
