I’m looking for info on the Form1+ lead screw. The short version of the story is that the refurbed replacement that Formlabs sent me for my machine has never printed properly (there is a repeating wave in all prints) they had me try cleaning mirrors, replace mirrors, new vat, new resin, old vat and so on. I told them about a visible wobble in the lead screw but this was dismissed by them. So, after having it basically collecting dust for another year I’ve decided to fix it myself.
Formlabs said they don’t have the specs on the lead screw and to check here. I’ve removed it from the stepper motor and now just need to buy a replacement, but there is some info I need on it to get the right replacement.
I know it’s a T8 screw with 2 degree thread pitch, but I need to know the lead and if it’s single, double or 4 start? Anyone know?
Better yet anyone have a Form1 or 1+ they are parting out?
