Esun black petg kicking my hiney

Post by desman » Sat Aug 01, 2015 6:22 pm

Getting it to stick to the purple glue this morning so I could calibrate it had me pulling my hair out. I went as high as 255c but it seemed to be bubbling so I dropped back to 245c and 90c bed. I finally brought the skirt to zero offset and was able to get it to stick long enough to print the cube outline. I just sprayed the glass with aquanet so I will see how it sticks to that. Speed is at 3600 mm/min. and first layer is at 50%. I read and reread the esun petg thread and that only makes it more frustrating when you cannot get it to work of yourself.

Several even coats of hairspray, sprayed on the glass while it is cold, works pretty well. I had really good luck doing the hairspray over Kapton tape, with bed temp of 85°.

And I hate to say it, because it costs more $$$, but my favorite by far has been that Zebra plate. Just run the temp in the 85-87° range, and you don't need to do anything else except let it cool before removing the print. (Which then pops right off with no drama.) :D

I run the black petg at 250 and 75 with Elmers purple glue and it sticks great. Are you putting the glue stick on heavy or light?

What I do is when the bed is cold (and clean) I put it on real light in two coats. The first coat running forward to back back then switch to left right when applying the second coat. (these are done back to back never picking up the stick.) I then heat the bed up and it should be dry by the time it gets to temp. Haven't had any problems since trying the glue stick I use it for ABS too. Once it cools down and you hear some cracking sounds you know its time to get your print.

I'm over here like "I print PETG black on bare glass and it sticks too good...."

100C bed temp (even worked at 90C),keep it squeaky clean. get it level and the z-offset right, you will have no problems.

I put a purple glue stick in a small plastic bottle with a anteater spout. I then add distilled water and use that each time I print. Just squirt out a puddle and wipe it around the bed's surface with an old pair of underwear. It works great! Your are welcomed in advance...

Yeah, that icon of yours is a pretty vivid reminder! :shock: :(

(Never gave me a bit of trouble with PETG though - I think it comes off easier than ABS.)
