I have an giga and it’s a bit finicky, I am hoping to troubleshoot. A Bambu it is not. I am a bit disappointed, because for bigger prints the printer is much less reliable so far than hoped. I had desired to be doing much more furniture design prototyping and projects than troubleshooting.
My primary issues are bed adhesion (even after good bed leveling), and layer adhesion. The first, leads to a quick failed print and sometimes a more catastrophic clog of the nozzle. The second, yields a bad quality print that has warping.
Right now I can sort of print PLA with a lot of brims (no brims, no joy) but my desired state is to print PETG, but the issues are proving too severe to get any success there.
I’ve done temperature towers, and am running hotter with a 0.6mm nozzle. I have textured pei print beds.
Anyone have any suggestions?
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.
Put it in the freezer or outside if it's cold out. Will pop off on its own a lot of the time.
