V1 upgraded to V3 hybrid now extruder will not work

[Mrclaybo]

Helped a friend add v3 skates, ball arms, prebuilt HE280 and new 12v 29amp P/S. Everything is working but the extruder. It is not moving at all. No torque i can spin by hand. Moved E0 motor to X axis and it moves so not motor. X motor will not turn on E0. Installed latest firmware. Did change current levels to go with older motors. Tried extruder cold with no filement and with HE280 up at 200deg... Unit was working perfect befor upgrading. Motor connectors were only unplugged from Rambo and plugged back in after upgrade...any ideas?

What printer did you choose in the firmware?
and this might be silly but Rambo accepts two Z motors, make sure yours is connected to E0 and not Z or E1.

Selected V2 and confirmed in E0. Tried in E1 just to see as well. Is there a way to tell firmware to use the E1 port on the Rambo? I can try that for troubleshooting to see if I lost a port some how.

You can swap the pins for E0 and E1 in pins.h, then plug in to E1 if you want to test that. The rambo will still call it E0
