Worst CNC shield 12v /24 volt board GRBL v4 Arduino Nano (Problems, fix, Mods, flaws, corrections)

Описание к видео Worst CNC shield 12v /24 volt board GRBL v4 Arduino Nano (Problems, fix, Mods, flaws, corrections)

The CNC Shield GRBL v4 board is plagued with design issues. This video explains the issues and how to solve some of them.

1. Missing motor jumpers
2. Two different voltages, warning anything over 12 volts to 24 volts must be supplied by the pin input not the power connector as this is 12 volts max.
3. Microstepping doesn't work and will not work unless the circuit is altered.
4. Arduino pins are incorrect for x,y,z step.
5. Arduino probably a fake so will need additional drivers to recognise COM port.
