Comment on (Troubleshooting) Does anyone have an elegoo giga?

I don’t own one of these but I took a look at the specks and I’m pretty confident I can give you some pointers.

First and foremost, you need an enclosure petg is going to cool way too fast if they thing is open air. My best advice would be to shove it in a closet or build a cabinet around it if you’re so inclined. The mega printer I’m working on is going in a converted curio hutch.

Second, there’s never enough adhesion. If you’re running pla, put a good layer of pva glue down on your bed before a print. Between that, texture and brim you should get a hold. If you’re not worried about playing fast and loose, you can print your first layer tight to the table for just a smidge more grab.

Lastly, I think the other poster is right about speed, taller parts get shakey. The housing will help with this by preventing ambient drafts, and you can use to to prevent frame shake if it’s sturdy enough, but going slow is always a good idea.

False…I have a buildtak plate that I stopped using, it will literally stick so well that the layeror two stays on the plate when you try to remove a print.

  I might have to try some of this buildtak.

I think you might have nailed it on advice. Based on what you and others are saying it sounds like an enclosure is in order.

I was wondering about glue? I’ve been using it on the build plate on the giga. To be honest though, I don’t even bother gluing pla or PETG prints on my smaller printers that have textured PEI build plates.
Understandably though, it makes sense the larger build area and lack of enclosure would make adhesion more difficult.

I noticed a bit of wobble when it was printing the arches at higher heights. I think you are again right in that speed needs to be reduced.

  I was thinking about it after posting and if you’re not hurting for plastic you could reduce some of the wobble by adding temporary support to the model. Cura used to have a plugin called baobab that would auto generate fat tree support all the way around a model, something like that to add extra footprint to taller models would do wonders.
