Hi,
I’ve got a grblShield v3. It works nicely with grbl github code but I cannot make G28 command to home any of my axis.
I have pins 9,10,11 wired to NO switches to GND. I have no pullup resistors to VCC nor I could figure out if they are needed or not (I guess they are as internal pullups does not seem to be set in limits_init() ).
Could you please guide me on how to get that working? (I have not used grblShield github code, maybe I should start there?)
Thanks a lot,
misan
