The fuser system is working now – and no fires yet! But WOW do halogens get hot!
… but now I have piston troubles.
Varying humidity (humidity really puts the ‘multi-dimension’ in MDF!) and sugar migration into the piston seams has locked up my NEMA 17 based pistons.
I can disconnect the motor and move the pistons by hand, but this will not do for a real build.
I’m considering either going the NEMA 23 route (with bigger motors will also come bigger drivers, and more electronics rework), or trying some loose-fit seal ideas I have.
Any experience here with piston success/failure modes?
