So far the print with airscape settings is looking pretty good!

Print finished beautifully - thanks airscape! Would you mind giving us your thoughts on *why* the settings you developed work so well for PETG? They seem a bit counterintuitive, especially the 'no cooling' part

TIA,

Frank

I had read that in the eSun specs someplace and on different websites when I started with PETG. I don't use it for anything but mechanical items that need to be strong yet flexible, they are normally simple shapes. I do make a cover for a knife sharpener strop that is a single .8mm wall using the .75 nozzle that turn out great with PETG. These print sequentially at 15mmS with no retraction.
They look bumpy but that is just the strip of LEDs reflecting off the shiny PETG
I think most of your issues was probably printing too fast with to much extrusion multiplier. Just compare what you had done with what worked.. retraction would not cause the problem you had.. but speed. too much plastic and the wrong heat.. not sure what temp you were using when you had failures but look hot to me.

Thanks for the advice airscapes. Changing my bed to glass and using sequential printing has made a big difference in my workflow. :D
