I got the printer, and assembled it step by step, nice and easy. i took my time because i really wanted to learn as much as possible about the printer and how everything Works.
then it keept underekstruding because the ekstrudermotor just keept "clicking" instead of running.
I did all that i could and had evry single ajustment in Cura under inspection, nothing happened.
I did not expect the software to make the mistakes, so i brought the printer to the shop, and they "fixed" it, believing that my filament ajustment was too tight.
I got the printer home, same problem.
Brought it back to the shop and they analysed evrything, and nothing seemed to be wrong with the assembly, hardware or firmware.
The guy in the shop said that it was only my files that made the problem. it worked fine when they printed items from their computers.
When i brought my printer to the shop, the NeXT days they keept getting new printers with the same problem, underekstrusion and a feedermotor that just keept "clicking".
the only thing we all had in common was Cura 15.04.02 or later.
Thats why i can only believe that the slicer in Cura makes some trouble with the feedermotor.
Now i have absolutely no problems printing wery nice stuff with Repeter Host. Im kinda tech freek, so the ekstra settings in Repeter suits me fine.
And altso. i dont use the cheap filament stuff. in my opinion, if you dont have the Money to spend on something, its not worth it. so why settle just to save a few bucks...
