@mooklepticon Just printing my first #PETG on #Ender
70°C bed
260°C nozzle on the bed
225°C nozzle afterwards
The difference from defaults is huge 😀
Edit: I also attached a pic, but for some reason it did not federated. Let's try a link then schmaker.eu/photos/schmaker/im…
Wow, that's a huge difference between 1st layer and later! I've never seen that big a delta.
@mooklepticon
I think my Z-offset is too high and I'm compensating it with temperature, but I don't care - nozzle cleans itself well, prints well and even structure is good.
When it works, don't touch it 😀
I generally print first layer at 260/250 and the latter ones 10 degrees colder. I do the same with the build plate - starting with 90, and leaving it at 80 throughout the ret of the print. With some plates you have to bee mindful of PETG sticking too well (possibly damaging them) but it works out really well with PET/PEO plates, letting the print retain the texture of the build plate. On PEI I either print it cooler, or use glue (in this case it makes it easier to separate the print from the plate).
@spitfire When I fine-tuned my settings I got a lot of stringing until I reached 225°C for some reason. Maybe it's vendor-specific 😀
Maybe you should try thoroughly drying it, that helps a lot with PETG.
