Hi,
I need some guidance in making a 3d printer using arduino uno and cnc shield v3. i have purchased all the parts and put majority together, but am stuck in wiring up the heater head. any guidance will be immensely helpful.
thanks.

printing bed and extruder heat sensors should be connected to the arduino based board using jumper pins, external 12 v (depends on the heater) supply should be provided for heating up the (bed and extruder) filaments. What board are you using? is it a Trigorilla?

I hope you are aware about G and M codes and arduino IDE serial monitor.

thanks!
i am using arduino uno, cnc shield v3,external smps 12 v supply, tray table made using three dvd drive stepper motors, a4988 motor drivers
my question is how to connect the heater. do i need a separate circuit for this?

i am aware of using the IDE.i am learning how to load GRBL.
