So I could use a hand. Just started getting my printer going.
The first two layers look great. Smear nice and smooth. After that it does this…

Would be nice to know a few things like the material you are using for starters.

Jason_Tira · February 16, 2017, 2:19am

Haha sorry. Abs. Heating to 255, bed at 100.

Thomas_Cox · February 16, 2017, 2:52am

Back the extruder temp down a bit. 255 seems really high.

Jason_Tira · February 16, 2017, 2:52am

A bit like 250?

Nate_T · February 16, 2017, 3:49am

Try 240.

Jason_Tira · February 16, 2017, 3:50am

Will do. I’ll update.

I’ve seen that if the z offset is too low. Pressure builds up in the nozzle, it oozes out the side. Could also happen if your z steps per mm is off.

Josef_Jelinek · February 16, 2017, 4:28am

it seems like you are exteuding too little and the first layer is very low so it may be sufficient for a it, but not for higher or the back pressure blocks the hotend or the extruder…

David_Clunie · February 16, 2017, 4:38am

if the first layers go down, check to see if cooling fan goes on, fan should be off, also check the model go layer by layer in preview and see if something is amiss.

Greetings Jason, not knowing any details outside of the image you provided, it looks like it could be speed and temperature. Make sure to look at your filament package and maybe make your temp between the high and low values somewhere in the middle of the two. Then you can increase or decrease your temp to determine what works best. With speed maybe try slow first for a few layers then crank it up after you see good layer adhesion. These are settings I use when I print with ABS so hope this helps.
Temp. - 237
Bed. 80, layer height - 0.20 to 0.25mm
Speed. - Extruding - 50 mms
Speed Traveling 40-60 mms

-Take care

This all helps tons. Thanks everyone!

I agree with Josef. I had prints looking like that because my geared extruder had steps of a direct extruder. Having only 1/7th the required steps would cause little clump farm.
Looking at your skirt, I agree that your first layer is too thin.

Gonzalo_Aguilar_Delg · February 16, 2017, 8:15am

The extruder is not pushing the plastic hard enough or you have temperature too low…

So have changed a bunch of settings. Got much closer! Had some issues on a couple areas due to cold bed, accidentally lowered it to 80, areas not sticking.
