I’m not sure where to turn next., this is my Dad’s printer, he has no clue, I have only a little bit more having built and use a Voron at work.
He tells me it was printing ok but the he had a filament clog.
Board: V4.2.2
Firmware: V.1.4.7_G
He found a broken wire on the extruder fan, soldered, still no movement from the fan.
Purchased a complete new hot end but no change.
Tested voltage to the hot end fan, <1v
Purchased a V4.2.7 board, flashed firmware again to V.1.4.7_G.
Fans now work, motors engage when selecting auto home but the hot end makes no effort to move, resulting in homing failed message.
He’s not wanting to spend any more money on it but I can’t help but feel there’s a simple solution out there, just not sure what I can do to help him.
