Printer does not home anymore

Recommended Posts

Please help me!

When homed manually and start printing, everything works fine, after printing the head moves left but not back.

When I try to home from the menu the head actually move short steps forward.

When pausing and continuing it resumes printing on completely wrong coordinates.

How on earth did this happen? Does anyone know how to solve this?

Sounds like you have a problem with you limit switch. It must think that the switch is being pressed in. Toggle the switch with your finger and listen and feel for a "click"

If it does not click then you have a faulty switch and will need replacing. If it does click you need to check the wiring, make sure it hasn't worn though or shorted somewhere. You may need to unplug it and check it with a meter to see if it giving an open / closed action when pressed.

If you download the ultimaker app there is a section for broken x / y switches under trouble shooting. Or you can look Here

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
