Recently, I bought an used Objet30 pro. I ordered brand new printing materials at a verified stratasys reseller.
When I started my first print, it started perfectly fine; the machine was building the part layer by layer. However, after a few dozen layers (I think about 50), the printer started printing layers randomly around the object (most are misplaced in the X direction, but some are also misplaced in both the X and the Y direction). After this print, I restarted both my 3D printer and my server computer and sent a new job to the printer. This time the printer misplaced the layers from beginning.
I contacted my stratasys reseller and they told me they had never seen this issue. They suspect either the optical cable or the Z-encoder is broken.
Has any of you ever had an issue like this? Does any of you know how this could be fixed?
