Comment on How do I make this work? Or should I give up?

I don’t think I have the necessary experience required to properly diagnose your issue(s), but I troubleshoot hardware and void warranties for a living, so hopefully my general advice can be useful:

The obvious part is to start troubleshooting from one end. And when “nothing” works, the correct end to start from is the end with least variables, so we’re talking very basics here. And from that you can tackle each problem as you properly confirm them.

So the first thing I’d do is to check that your temp settings are good for your filament. And can you verify that the temp shown is in fact the actual temp? Could be a busted thermistor. All checks out? Well, your hot end is probably find.

Next up, are you able to confirm that the extruded amount of plastic matches what should be extruded? I had a recent issue of over, trudging myself, and if this isn’t dialed in correctly it can get really messy, especially with PETG.

Any chance the nozzle is damaged? If it’s out of shape in the literal sense, it will be unable to lay down plastic in a precise manner.

And then there’s the part I always hated: Heatbed leveling. First, your heatbed needs to be level relative to your X and Y. The tiniest inaccuracy will make the whole project a nightmare. Precision calipers are your friend here.

Now, heatbed temperature, check the same stuff as you did with the nozzle. Correct temp set for the material? And is this the actual temp?

Now it’s time to ensure the Z offset of your nozzle is correct. Too high and it’ll just string instead of what it’s supposed to do. Too low and you end up with what I call nozzlesnot which can cause symptoms similar to a damaged nozzle, which might also have stringing as an end result.

If you made it this far, your printer is probably mechanically fine, so it might be environmental factors such as ambient temperatures. Also, I remember back in the day that some had issues with various filament manufacturers being really sloppy when making filament, resulting in varying diameter.

I don’t do PLA myself, so I won’t comment on print surface or your temperature choices.

Anyway, I hope this helps. Either way, I hope you get to the bottom of it.
