Hi, folks!
Yesterday we got our new Ultimaker 2. The calibration was successful, a flash card was copied file, and started printing. But after 20 minutes of operation printhead suddenly shifted along one of the axes is more than 20 millimeters, and eventually display a message about a problem with one of the axes.
I saw a thread on the forum with a similar problem, but the difference is that no modifications printer in our case were not carried. Visually no damage is observed, reset to factory settings and firmware upgrade to the latest version gave no results. The impression that the stepping motor above the feeder operates in one direction only.Are there any ideas on how you can quickly fix this bug?
