Upgrade I3 Pro W to dual Extruder
I want to upgrade my printer with a dual Extruder with a 2-in and 1-out hotend. I bought this one: https://www.geeetech.com/2-in-1-out-dua ... -1038.html and also a second stepper motor and the driver.
The problem I have now is that I don´t know how i have to reprogram my printersoftware. I need two steppers but only one thermistor.
Do you have any ideas how to do this?
