Anet A8 extrusion problems

[Cos211]

Hi everybody!

I bought my Anet A8 some weeks ago, everything went pretty good until I decided to switch to 0.2mm nozzle. Now I can’t get it to work good again. I tried to level the bed in the best way possible (and I think I’ll switch to something automatic as soon as I can, because using paper to level it it’s awful), but no filament was coming out. I thought it was because the bed was too near to the nozzle so I tried to lower it while printing, but the filament wasn’t sticking good.

Tried to level the bed again and in the picture you can see the results in the filament. Any idea why it’s doing that?

The material is PLA, printing at 35mm/s, 210° the extruder (value found on the filament box) and 70° the bed, 125% flow.

Thank you very much!

the filament will usually have a range printed on it or the box.

try slowing the print down to 10-15mm/s on the first layer or 2. you shouldnt have to increase the flow in order for it to stick.

it is possible that you have a .4 or .3mm nozzle that was mislabeled. happened to me once.

There’s no point printing at 0.2mm. The smallest you should use is 0.3mm - I often have a 0.6mm in my printer since it gets the plastic out quickly and for most of the stuff I do, it’s perfectly fine.

I wanted something with a bit more precision that 0.4mm, so I was trying something new. If it doesn’t work I’ll probably go back to 0.4mm (which I managed to use) or 0.3mm.

I’ll post an update as soon as I try this. Thank you very much!

It says 190-210°C. Would it be better to print a little bit colder than 210°C?

increase temperature and speed or turn off fan; otherwise the filament may block beacause of too low flow speed and it solidify before exit from nozzle.
