Axis goes to wrong direction

If you are using I3 PRUSA pro B/W/X.

Ⅰ. Z axis goes up when you home your printer.

1. The first thing you need to do is checking the Z axis endstop cable connection. make sure you have assembled it correctly. You can replug the connector in case there is a poor connection. You can move Z axis in the middle height ,then home Z axis, then press Z axis endstop manually and check whether Z axis can stop or not, if it can not stop, you need check the endstop. If it stops you can change firmware(the fouth picture).

2. Then you need check the cable connection on your main board.

3. If connection is fine, you can swap the Z axis driver with X axis driver(it should function well), if Z axis works well and X axis doesn't work well after swapping, there is a driver problem. To solve that, you can change the firmware "define INVERT Z DIR false" into "define INVERT Z DIR true".



Ⅱ. Z axis does not stop when it reach the bottom.

make sure you have assembled the screw and the length is long enough to hit the endstop

Ⅲ. X and Y axis do not stop even hit the endstop when home the printer, and make noise. and they only go to the opposite direction of endstop.

1. Check your endsop cable connector on your mainboard. Make sure you have assembled endstop correctly.
2. If endstop is ok, you can swap the X axis driver with X axis driver, if if X axis works well and Z axis only goes to one direction after swapping, there is a driver problem.
