Hi, I did the extruder test today, because I have problems with my prints since some time. Holes and stripes, at 230 C. When I bought the printer in Feb, it printed fine, even at 210 C. Last april I made a print of my son's head (was very good at 210 C) and I reprinted this same gcode today with 230 C : lots of horizontal stripes/banding (not really sure how to call it, I am Dutch). I added a picture of both prints. I also have holes in prints but not in this one. When I prints slower, mostly I do not have holes, but still have horizontal stripes.
The extruder test is a bit strange, maybe you can explain ? It is really very bad at 3 and 4, then it gets better at 6, 7 , 8 and 9 , and 10 is a bit worse but still not too bad.
Yesterday and this morning before the extruder test, I leveled the bed using the rings. I send you photo's of the last result also : it looks ok to me but I am not sure how to interpret the total ; in the back of the UM it prints a bit less I think ?
Note : tried to add the pictures but I could not figure out how to.... :???:
