Calibration file for ABS et al
Hello All,
newbie to printing here, I am switching to ABS after almost finishing the bundled PLA, but would like some advice:
Below you will find the gcode with my annotations: I have changed the temps to the ones suggested by Josef in the material guide, but I am not sure if that is all that is needed? Any advice on tweaking to be done regarding extrusion, feedrate or any other parameters? (even though I guess it's Slic3r doing all the work behind the scenes...)
I am more interested in the why than the specifics of ABS calibration (and any link to information is more than well accepted!)
Thanks in advance
Ulli

Re: Calibration file for ABS et al
Hi Ulli,
I dumped ABS for two reasons,
1, the fumes caused me terrible breathing issues, my chest took ages to recover after printing ABS
2, without an enclosure i was getting terrible shrinkage and intr layer bonding.
I now use PETG

Hi Joan,
PETG (e-Sun transparent green) was my first choice, but switched to ABS after quite bit of hassle with the stickiness and overall mess it tends to create.
I am a bit disappointed as I need to print some mechanically stressed parts and after reading opinions like yours it seemed like one of the best choices.
(I bought a roll of PETG, one of ABS and one of Nylon that I'm saving for last as it is horribly expensive to learn how to print on)
How do you deal with the stickiness? Whenever I print PETG I am terrified of leaving the room: as soon as I stop looking it somehow finds a way to tangle itself into a horrible mess. I tried default Prusa settings, googled, lowered the extrusion multiplier, googled again, played with temperatures... then I gave up and changed to ABS which by contrast is almost as easy as PLA if not for the very slight warping that I have to learn to correct...
Thanks for the advice, I will definitely be aware of the fumes and ventilate the room as much as possible.
