I’m sorry for misunderstanding me, but I didn’t mean 0,38/0,34mm instead the right extrusion width is 0,38-0,40mm. You understood everything else correctly. Green or white would be best for me to inspect the print by looking at pictures. -Marius

So just to get it right i have a 0.35 nozzle should i try to set extrusion width higher or lower?

or should i use flow tweak settings instead?

coasting… can you explain what that means so i can find the similar setting in kisslicer?

but so far i have upped each layer time to 15s

and upped temps by 5C… first layer 185 and the rest 180

bed temp is set to 60, if i go lower nothing sticks… mind you i’m printing directly on glass (ikea mirror)

what speed should i use? currently i have set X and Y to 250 mm/s… first layer 10mm/s and it adds 3 for each layer after the first one. accelleration is set to 2000 mm/s^2

If you use the 0.35mm nozzles you should increase the extrusion width to 0.38-0.40mm since the filament line will flatten out due to gravity. I have best results using 0.40mm width in the settings. Good luck, Marius

Coasting (a value set in mm) means, that the printer stops extruding for a certain length before going into a retraction. If you enable this you compensate the possible oozing when the printhead moves to another location. I have used 20mm/s as print speed and 10mm/s for the first layer. I also print on a glass plate and smear some glue stivk stick (solvent free) on the plate when it heats up. This creates a really good sticky surface, you might even need to use a knife or blade to remove the print. A small, barely visible layer of glue is all you need. Marius

still printing spares (gear wheel for extruder - old one is worn)

but there is no setting like what you descripe… so i will have to make do with playing arround with how much suck it does before a move to a new place… and how far or little it has to move before it considers a new location… but i feel a bit more wise at least…

watching the video now…

By extrusion length you mean the steps pr mm for the extruder right? Yes i got that one spot on :smiley:

btw… if there are some terms you cant explain well in english but better in german give it a go, i can read german no problem, its more my spoken german and written that are not good

Did you make another print with those settings ? Another thing that might help and is pretty obvious is that you need a clean nozzle, if yours is full of filament blobs etc. heat it up to ~150°C (depending on filament) and brush the extruder with a brass brush. I usually clean the nozzle and heater block while it is heating for the next printjob. Depending on the extruder you have you should be very carefull and use a soft brass brush, however this wouldnt clean up as fast

yep i printed with those settings and have not had any issues since…

about the nozzle… yep i clean mine too, its easy to spot if blobs has formed… i just use a small nail scissor and gently scrape from from top to bottom where filament comes out… in many cases i aim to do this at 150 where all the filament comes off in one ball of “goo”
