UM2 layer shift and Homing limit switch fail

Recommended Posts

Hi guys, I came home tonight to find a couple of issues.

Firstly, dreaded layer shift. Parts are still stuck firmly to the bed, but the print has shifted about 8mm back in Y

This has happened before, but I still haven't found the cause for it.

Also, watch the video, the head isn't stopping when being homed all of a sudden.

I can make the switch "click" if I manipulate it with long nosed pliers, but the head just wont trigger it, I've tried bending the tab out, but to no avail.

Any ideas on either issue would be great.

I guess so, must have bee quite a lot of load on the motors if it stalled / hung it up enough to cause such a shift. It's printing fine now though.

I thought I was being a bit ambitious printing 4 parts at once.



I think it's all the same problem... Perhaps an overhanging part of your print curled/blobbed enough to catch on the print head, bending the fan and causing skipped steps at the same time?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
