Hi, my filament petg looks weird, what’s going on for this to happen? Temp is set up as recommended…220-250. Filament is on the dryer 30 min. before printing and while printing also. ![20260121_144927](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/1/15f1f9e4057997a66ba5e95677dc63672e457a4e.jpeg) ![20260121_142421](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/a/af1f96811414cb3281871588502578e3d115c5b4.jpeg) ---

To my eye it looks like your nozzle is too close to the bed. What is your first layer thickness? Does the 2nd layer print better? Could also be a extruder issue where the filament is slipping on the feed roller or the roller is slipping on the shaft. Have you fitted the spacer in your extruder to keep the shaft from moving off center? > **[SV08 Extruder fix by Valerie Moore | Download free STL model | Printables.com](https://www.printables.com/model/968689-sv08-extruder-fix)** ---

1st layer thickness 0.2 ….2nd layer i stop before it starts….i had good printings before with same petg same set up ---

First layer is governed by your Z calibration and bed level, 0.2 is merely the software target. The manual should have steps to calibrate, traditionally a sheet of paper is used, lowering nozzle till it drags and setting zero. It can take many hours to dry a wet roll initially, but rarely would damp be so dramatic, normally just stringy ect, not complete failure. But watch the nozzle extrude mid air at hottest end of temperatures for the PETG roll you have, if you see bubbles or it refuses to go straight down that might be an indicator something is wrong there. Outer lines look ok, so check your bottom infill settings, line width, extrusion and most likely excessive speeds. I run the bottom layer at only 100mm/s and hotter to stick well. If its not adhering to the bed it gets dragged bulldozing and balling up other filament that had stuck. Check bed temperature is 70-90 and part cooling is off for first layer… should be by defult but its easy to bump a setting and not realize. While it might sound stupid, just try moving the part on the bed in your slicer. This will engage a lot more factors than you assume (its not just chance of hidden contamination like finger oils, its the height vs the bed-mesh when hot, possibility of a grab at an angle feeding filament ect ect, easier to diagnose these issues later if you can print somewhere else). If none of that works your up for something more drastic. Things like nozzle clogs, extruder drive roller slipping or idler (misalignment will again cause excess feed pressure), excess resistance along the filament feed path ect as it can all cause under extrusion suddenly… but it can all also be ruled out of you throw your normal filament like PLA back into the printer and it runs fast/well. ---

after cleaning it’s working good…those outerlines you speak they’re called brim and I did not found specs about the way ther’re printed….Thanks ---

after some cleaning it’s working great…I’ve that fix I’m finishing the test and then I’ll print that …Thanks ---

looks like you need to level your print head. set your z offset then aux leveling and auto z-align then save it all.
