E1 Will not extrude

[Delanjp]

Replaced the Geeetech V3.1 main bourd on my A20M back in April 2021. Now cannot get E1 to operate. swapped the cable between E0 and E1 Fault moved to E0. Thus motor OK. Swaped the Stepper Driver board between E0 and E1, E1 Still not operating. PInned the cable to the motor. No issues all wires are pessent
Issues has to be the main board.
Checked the function of the Stepper drivers. On pin 2 of the Driver E(EN), the voltage goes to just under 5 v when the motor is enagaged on E0, When Enabling E1 no change in voltage. E1 Motor is not being turned on.
I am runing Vert-Marlin-vert-bugfix-2.0.x-a20m-testing, Putting back Geeetech Default 1.18 distro does no difference. Error persists. Any clues on whats wrong, Replacing the board last time was a pain.

This was working
