"Normal quality" problems

Post by keinarsson »

Hello,

I just got my printer recently and i have done a couple of prints.
My problem is with the draft quality and the normal quality options.
here is a print i made today on normal quality and this is the same problem i have with the draft qualty.
I have tried a range of temperatures and tried to play a little with the flow/feed rates.
I have no clue how to fix this.
Any advice?

It could be several things: partially blocked hot end or filament slipping (not tensioned enough)

This could be caused by the hot end nozzle being situated too far away from the hot bed when you start to print, resulting in too little bonding between the layers. Try to lower the z-homing even further. You could also test with increasing the flow since that should result in "fatter" layers = better bonding.

That 40x10 part is nice for testing the proper flowrate for whatever filament you use. Try to pull the layers apast with your fingers. If it brakes you need to up your flowrate until its solid. If itäs too much you get flattened layers wich is much harder to see but not such a big problem.

To me it looks like you might have a partially clogged hot end.
