One of the stepper motors’ switch things (the metal part that hits the bar to tell the motor it’s at one end of the track) came out and it’s either bent too much or snapped off (it’s so small I can’t really tell) and it doesn’t go back in place, which means I can’t use the printer because the motor with the head on it doesn’t know when it has reached the end of the track and just tries to keep going if I don’t stop it.
My first thought was to print a new piece but… That won’t work when I have to use the printer to do that. The motor itself is great. It’s just that stupid little metal triangle thing used to give the teeny tiny switch some more surface area to be pressed.
So. That’s definitely a micro switch, if you look to the left you can see a spacer/bracket. The switch usually has 2 through holes to screw to that bracket.
If your comfortable soldering, any similarly sized switch will work; but you can probably find replacement parts that are more or less pre-wired and just plug into the board.
You’ll have to adjust the end stop to get the homing correct; but its just fiddly, not difficult
