It's not just the LED though it seems. Now I've actually tried all the functions it seems there are 3 issues with this new board:
1) No LED coming on at all. Not once.
2) The extruder stepper does not run when I tell it to feed/reverse the filament (is there anything in the repetier software that would prevent the extruder stepper from moving?)
3) The Z axis moves extremely slowly, and 'judders'. I've tried cautiously increasing the vref on the z axis a little at a time but it still behaves the same.
