Hi, I will complete the tutorial as soon as possible.
If you have the stainless steel print bed, it could be easier tho keep the objects attached.
I never used the glue. I use the airspray every time. When you go to buy it, keep in mind that the cheaper you buy, the better it paste.
Avoid to buy too high quality hair spray. I don’t know the brands you have in USA, so I have no suggestion to give you, but you can ask to somenone in your area.
Pay attention to bed levelling: too high distance from printing bed and nozzle on first layer can cause detachments.
Anyway: If you print PLA you can add from 5 to 15 brim loops. I use RAFT very rarely, never used with PLA.
If you print ABS or other more difficult filaments, use 15-20 loops of brim and more spray on the base.
There are no fixed rules, it depends from type of filament, temperatures, fan settings, shape of the object, etc.
For PLA and PET-G keep the fan settings 30-60%. For ABS, Nylon, ecc keep fan settings 10-40%.
However, the life of 3D printers dedicated people to is a life of experiments: each release should be analyzed individually.
I hope this will help. All the best. Enrico
