Part Cooling Fan and extrusion issues

Hi all, purchased my vcore 3.1 back in May last year. Upgraded a few parts and began setting up, had some issues and then got super busy. I'm now trying to tackle it again and could really do with some help.

The printer has the Rapido hotend, LGX-Lite and the ebb36 v1.2 board.

Issue 1) my part cooling fan only seems to want to turn on at 91% when controlled via slider in the dashboard, that doesn't seem right to me? lol

printer.cfg has this:
[fan]
pin: !toolboard:fan_part_cooling_pin
cycle_time: 0.00004


toolboard config has:
[board_pins btt-ebb36-12]
mcu: toolboard
aliases:
    # fans
    fan_part_cooling_pin=PA0,
    fan_toolhead_cooling_pin=PA1


Happy to upload config files if required.

Issue 2) Filament doesn't want to extrude when trying to do a tuning tower test print for my pressure advance. If I just extrude filament using the dashboard it extrudes OK, although sometimes it does 'click' as though it is skipping if that makes sense

Any help really appreciated.
