Hi folks,

after buying new filament and moving into a new home, I’ve had to recalibrate my printer to some extent. Z-axis was off, the new filament is about 2.9 or 2.95 mm thick instead of 3.1 mm like the filament I had before.

I’ve left nearly all settings like before. All that I’ve tweaked in Slic3r is filament thickness and flow rate. The prints with the old filament looked quite nice. With the new filament (from a different manufacturer) it now looks like this.

Any idea what causes the structural inconsistancy near the holes and above it? Material thickness in the affected area of the part is about 5 mm.

(By the way: the visible offset in the top layer of the flat area was most likely be caused by an erroneously triggering end stop switch. I could solve that during the print by pausing, re-homing x and y and continuing the print. But that’s a different story.)

Thanks a lot!

Cheers,
Hendrik

I’ve figured that my hotend was loose… It’s a Velleman K8200 stock extruder and the screws of the hotend tend to loosen probably due to vibrations. I’ll see if this solves above mentioned problem. The first layers of my current print look promising.

sometimes the diameter vary on the spool and you get that Problem.

To correct this error should measure the diameter of the filament at several points of the spool and do the arithmetic mean total
