small features turning into blobs - PETG printing
I'm having trouble getting things to print that have small features alone on a vertical section. For example, the nut holder on the fan shroud - the last several layers or just the nut holder and while the rest of the print looks fine, this section looks like it melted into a bit of a blob.
I also had similar issues with a rabbit model with thin ears sticking up by themselves.
Is there a setting I need to change? I've already reduced the temperature to 225C and the rest of the print looks fine, not stringing etc.
RE: small features turning into blobs - PETG printing
I think you need more part cooling on the tiny parts.
Cooling settings is under filament tab - to do more advanced settings as fan speed, you need to be in expert mode.
Try changing the settings under Cooling Thresholds.
Have a look at my models on Printables.com 😉
