Hi I have an ultimaker printer and I have had quite a lot of problems with it. The first layer is not being printed out properly and is causing errors in the rest of my design to be printed. It seems to be that one way it will print each line completely next to each other, in the other direction it does not seem to print properly. I will include pictures later on. It seems to me that it may have something to do with the code, but the other day it printed perfectly and now it is not printing the same way and I have not adjusted the code. I have tried levelling the bed over 10 times, I have tried with different distances away from the nozzle, I have used a spirit level to make sure the bed is level, I have wiped down the base with nail vanish removed to adjust the sticking, I have wiped down the nozzle and have checked everything. I have even adjusted the temperature and the speed at which my object is being printed, but it is still effecting the overall object. I do not think that the nozle is releasing any filament on the back stroke in one direction, does anyone have any ideas as to why this could be? Thanks!
