I used the printer for 11 months now, and ther are still problems. First the what i discribed above. Now it is comming back. I use a other brand of filament (3Djake). Worst than this is not thinkeble.
But i notice also mechanical problems; the liniaer rails (X-axis) are running heavy on surtain points. The Y-axis had this from beginning, some rumbeling noises. I thought it is new, it suppose to be like this. The y-axis is doing it now too. It is noticeble when the printhead moves suddenly fast. It skips/slips over the gear.
A produckt that works less than 11 months… never worked well… printing a total of 5 kg, which thrown away of 3-4 kg of mishaps. Good score!
I still thought that my printer is a piece of garbage and now i know it is so.
