I don’t use glue, I did try hairspray when I had the mirror but found the mirror was just as good on its own.
I now use an Anycubic Ultrabase and give it a good clean with isopropyl alcohol before printing.
It wouldn’t do any harm if you wanted to, but there’s no rush, I have a custom made bed that I made, it uses double sided copper clad PCB glued down to the Ali plate with 3M scotch mount and topped with glass which is also 3M’ed too. These are all mods that came to light from having the printer in the first six months.
Just take your time to learn your printer then take the next steps.
The R visible in the picture is to let you know Right from Left when setting up which nozzle to use…
Nearly forgot, the printer comes with spool holders, they are rubbish, there’s lots on thingiverse specifically for CTC but I opted for two storage boxes, M8 threaded rod 2 bearing and washers.
