Please help with the dxc2

Hi all. Just installed the dxc2 (followed video) and installed the code… the bin one was there to be changed, the other one wasn’t, so I skipped it as it said.

I started to print a bench and it started fine… then stopped extruding… now it won’t retract, or go back to the cfs, with the usual warning… can’t return to cfs etc…

Can anyone help? I’ve also changed the cutter to stock and did nothing, so swapped back to the one that came with the dxc2.

Honestly, I’m going crazy
