Winter Temperatures

Greetings 

I'm having great trouble with prusament petg. It sticks to nozzle, fuzzes up, stringing and ozzing. Basically everything except lifting from the bead. The first layer distance is good and the bead is clean and level. The filament is quite new, and stayed in enclosure the whole time since opened. Oh and it's the one for printing face shields. 

Could it be the cold. My printer is in a wood workshop (wooden structure) that is not heated and badly insulated. Printer is in an enclosure, pretty much an air tight one. 

Before printing I need to heat the chamber (min temp error). I do not have an thermistor in the enclosure. Any tips for one that would connect to octoprint?

PRINTING IN AN UNHEATED ROOM IN WINTER? YAY OR NAY?

RE: Winter Temperatures

PETG is very sticky and will stick to nozzle, it self and bed.

If you are using the smooth building PEI plate, you need to coat it with thin layer of glue stick, soap or windows cleaner for easy removal after print. I use windows cleaner before every PETG print on the smooth PEI.
The textured PEI just needs to be clean.

Hey thnx for the reply already know about the sticky situation 🙂 . It's hard to remove but not an issue for a strong boy.  

I did a temperature tower last night. And it's not good.

PS: How do you post proper pictures if I use insert/edit image I'm lost dont know how to ling from hard drive

 

I believe that there are layer separations below 230 °C Perhaps even there it's hard to see on this tower.

RE: Winter Temperatures

To me it looks like 225 - 230 will be the right temperature range.

To upload a picture to this forum just use the "Add Media" button, select Upload files and drag/drop. Select the media you want inserted from the media library and insert.

Next test was this thing ----> Teaching Tech. Really don't like using Prewritten G code. But I lack the knowledge to do something like that in Prusa slicer. Would also love to know how to do this---> Multi-Retraction Test


There are like no strings/hairs. Just those ugly bulges on the sides. Are those seams. Like the thing that you can select in slicer. I think it was set to aligned.

RE: Winter Temperatures

I get those bulges too when printing PETG - the extruder oozes when traveling between towers. More retraction or drying the filament could reduce it.
