The printing shifts suddenly and randomly in the middle of a layer
After many days since I received my P802N Prusa I3 3D printer i've able to assemble it and solve most of the usual problems except one.
When printing, for instance, the 40mm_box_pillar the head shifts suddenly and continues to print some milimeters away. If left alone it does that until trying to go out of the base.
I cann't find no reason for that because it doesn't happen on the same place. One time it did that on the first layer other times on the 3rd. The best time happened in the middle of the 9th layer.
It happens printing directly from the SD card or printing from the PC with of the Repetier-Server. I have to cut the power or stop the print job to prevent possible damages.
The printer data is:
Zonestar 3D Printer
I haven't change any settings.
The acceleration is set at 800,800,100 fo X,Y,Z.
Autolevel is on.
The belts are tight.
The base is levelled and covered with the paper tape supplied.
I'm using PLA 1.75mm filament.
Is this a good question?
