I’m getting ready to print a bunch of parts in PETG and this being my first time printing with it, I need to determine the best possible printing temp for my setup. (mostly stock Ender 3 Pro with a Micro Swiss hotend)
So here is my temp tower starting at 245 at the bottom and ending at 200 at the top. To me it looks like I should be anywhere from 230-240
I have an E3D with all metal hotend and I run at 250C - nice glossy shine.
One other recommendation if you are not already doing it - get a ‘pro’ style silicon sock, where only the very tip of the nozzle sticks out - it will reduce blobs and drags dramatically when printing PETG.
With my brittle PETG prints it’s usually heat or speed.
Heat generally helps layer adhesion overall, but I’ve found speed makes a bigger difference to me with PETG. If I slow it down a bit more than my PLA settings layers seem to adhere better.
@TurkeyOnRye thanks for the tip, I’m trying again with a temp increase of 10 deg hotter. currently I’m printing at 50 mm/s. If this doesn’t work I’ll try slowing things down
