Thanks a lot bro! You saved me from extensive hair loss. Will send you my pic with a nice hairstyle 👍😂

Ok, next time I will Google first and buy then.. couldn't believe that something so fundamental like step resolution selection is done wrongly.. thx for compiling your findings..

Thank you dear friend! You saved my CNC. Congratulations on sharing your knowledge ...

Nice, i ll do the same on my current cnc and see how it performs. Good video

[@urz7481]

so its better for buy cnc shield v3?

[@TitoFerreiro]

The noise that the motors make tell me that they are malfunctioning if they put the legs to VCC mode the operation of the motors changes radically, try it.

Did you try adjusting trimmer pot on drivers to set current?

[@designer9205]

GRBL version?

Спасибо.

[@mdeeen]

thanks

[@witptrhen4382]

good mini cnc check

[@PhoenixMAX2007]

you need to adjust the resistor for the motor driver with the right voltage for the motor

[@TitoFerreiro]

This shield v4 board has faulty mode connections as well as they are designed to have missing resistors to pull up the VCC voltage on the mode pins
