MK3 major issues
Just set up repetier server with my Prusa MK3. Whenever I print something using the server, it goes crazy on a layer change. It moves the extruder up and down maybe .02mm several times while extruding in one position (no xy change). After maybe 5 or 10 of these movements, it continues on with the rest of the layer fine. The problem is that this creates a large blob of filament at the change point (to the point that my print gets ruined).
The same exact g-code prints just fine if I print it directly from the SD card and don't use repetier.
