We started having an issue with our UMS5, whereas the build plate is dislodged to the right, at the end of the print. We observed the following: At the end of the print, the printer head moves all the way over to the left to purge a little material out and cool down the left side print core (i believe). At the same time, the bed raises to a higher point. After the left side is cooled, the printer head moves over to the right side to purge and cool down the other printer core. During the move to the right, the bed stays raised and the printer head collides with the printed part. Any ideas what might have caused this, or how to resolve?
