Comment on I like big beds and I cannot lie, pt 2. Any hints to improve ASA adhesion?

Chamber temps need to be higher for such a long skinny print because it will contract significantly lengthwise. The fun part is that if you get better bed adhesion without higher chamber temps then it could bend the whole bed sheet into a taco temporarily. Try setting your bed at 110C for an hour before printing with the part fan blowing on the center of the bed to help circulate the air.

Haha, I’ve seen tacoed mag bed photos and know exactly what! Pure talking about. I’m wondering if this size/aspect ratio is even possible. I’ve printed large round ASA parts with no issues, but don’t know what design patterns do/don’t lens themselves to the material.
I’ll have to try a longer heat soak. I’m also thinking I should try more bedfans…

I have the nevermore under my Voron2 300 and it still struggles with prints like you posted. Switching from ACM to Plexiglass panels helped improved insulation somewhat. The hack that I use in a pinch for big prints is a terrarium heat lamp with temp control hanging from the top of the printer.

Supposedly, the filter does a better job with air flow but in either case, two fairly small fans in a bigger enclosure seems destined for struggle.
A heat lamp isn’t a bad idea. Did it solve your warping issues? Before I go that route, I’m tempted to try adding two more bedfans first. I should also add a chamber thermostor vs just waiting for a fixed time period.
When you said switchfrom ACM to Plexiglass, I’m guessing you meant the other way around (eg you have ACM panels now)? Where did you get them?

The heat lamp did help for the couple parts I was having issues with. I now mostly use a mini trident for most of my ABS printing. The heat lamp only comes out when I need to do a large print on the Voron2.
There was a Nero3D (Canuck Creator) video a while back where he said acrylic is better at insulating than ACM so I went from ACM to acrylic. Plus the smoked translucent acrylic looks better. I bought the ACM from PrintedSolid originally and have since reused it for other projects.
