FREE PINS ON CNC SHIELD

Post by albert.cambras » Thu Oct 29, 2020 9:11 am

Hey, i'm trying to do a motorized slider and i have one question,
Iwould like to know if there some free PINS that are not used by the cnc shield.
I would like to put a LCD display and i have thrree motors with three drivers, could i use the pins that make references to end stop or any different pin to connect buttons or an LCD display?

Unfortunately GRBL fully utilizes all the pins...

So i can’t put any button or joystick to controlate the motors if i use the cnc shield?
Can i use the pins that make reference to end stop or any pin like SpinEn,SpnDir that i won’t use to connect a display or joystick?
Another solution would be use a protoboard and connect everything via cables?
