So I got myself 4 rolls of PETG HF 2 yellow 2 black and at first I was having extra strong adhesion on my stock A1 Build plate. I has been a few months since I got the A1 and nothing is sticking down now. I have to use glue sticks to promote adhesion and to release.
I have dried my filament on my Space PI at 60 degrees, for 6-7 hours and have not seen an improvement with adhesion. PLA + from Esun works just fine, sitcks down nicely but I have had no luck with Bambu PETG HF.
I’m using all of the right profiles on the slicer, PEI plate, .4 nozzle.
50% speed first layer. 70 degrees bed temperature but nothing seems to be working. I just ordered a BIQU Panda plate but it’s gonna take a week to get here and I need to print some things. What do I do?
Are you giving the plate a good scrub with hot water and anti-grease dish soap? I do that and then dry well with a microfiber cloth and rarely have issues.
If you can’t go to 65C in your dryer it could take 12 hours or more to properly dry a roll. The only way to know for sure is to weigh at intervals or test print.
You can bump the bed temp to 75C or more but I have not had to do that on textured plate, only for adhesion on the 3d effects plate which arent even supported with PETG-HF.
I did end up using a nozzle temp of 260C on the PETG-HF to avoid nozzle buildup, your env might vary.
I did give it a good wash at least every print and still having the same issues, I’ll try weighing the filament to see if it made any difference.
I set the bed temp to 75 and am printing multicolour. Small letters and stuff for a coaster but it’s still not the best adhesion. Had to cancel at least 5 prints so far.
Dried the filament again for a couple hours and RH% was at 13% so I reckon it was pretty dry but ill update if I see any improvements
