Biqu H2 on Sidewinder X1 - extruder not working

[pekohl]

I just ordered and installed the Biqu H2 and SKR 1.4 turbo board on my Sidewinder X1 v1. I'm having an issue getting it to extrude, when I warm up the nozzle and try to extrude the motor just grinds/clicks and the gear doesn't move.  If I try and 'help' it with my thumb on the gear it will spin but not smoothly. If i disable the motor and spin the gear manually it spins smoothly.  I've disassembled the extruder, cleaned all the gears and lubricated.

Here's a video: https://imgur.com/a/e4fjGWF

I'm running the latest Marlin Bugfix 2.0.x firmware and have checked the current on the motor:

#if AXIS_IS_TMC(E0)

#define E0_CURRENT 900

#define E0_MICROSTEPS 16

#define E0_RSENSE 0.11

#define E0_CHAIN_POS -1

//#define E0_INTERPOLATE true

//#define E0_HOLD_MULTIPLIER 0.5

#endif

Any assistance would be greatly appreciated, thanks.

Figured out the issue. One of the pins on the ribbon cable was shorted. I just replaced the ribbon cable and all is working now.
