need Help, maybe a defect in the Board ? extruder has problems with z-Axis
Hello guys, i need help with my Afinibot A3 Printer.
it has the long narrow Zonestar mainboard, its an older one with no auto leveling but it works great !
from one day to another it got an issue with the Z-Axis ! problem: it seems that the hight of the layers are not raising up correctly !!!
that causes prints that has only ca. 75% of the intended hight of the model and extreme over extrusion because of the reduced layers !
i didnt change anything and also old correctly worked gcode files has this issue, so it must be printer related.
is this a known problem ? is there a setup in the printer to correct this or via the small potentiometers on the board ?
Thanks so much !
