Geeetech i3 Pro C dual extruder

[tripalreno4]

Geeetech i3 pro c, I need help with the calibration of this machine. I can’t seem to get even my first layer to go down correctly. I’ve owned an ender-3 pro for almost 3 years and have a lot of experience. But the dual extruder is completely throwing me off. I will also add that I picked this printer up second hand and have not been able to get it to print with both extruders. I have gotten one extruder working before. I also upgraded the stepper driver motors, and haven’t got a good first layer down since. Do I need to change any firmware since I’ve done that?VidMate Mobdro
