I’ve wanted one of these for a while, decided to bite the bullet a couple days ago! Seeing as I was somewhat familiar with CAD software (from engineering classes several years ago) it seemed fairly straightforward.

As someone completely new to this, there have been a TON of things I’ve learned from binging 3d printing channels…

  • First layer adhesion 😭
  • Bed levelling
  • Types of extruders (bowden/direct) and how they affect what materials you can print
  • Tons of printing materials, personally will be using PETG and PLA
  • Keeping filament dry in a vacuum bag

And soo much more - but there is still a lot that I have absolutely no idea about.

The printer is a second-hand Flsun Q5, the seller sent it fully assembled (very, very brave of them, but it arrived unharmed). I had a brief look around at other options, but for the price of an easythreed, this was a no brainer.

I think the seller had some issues with bed adhesion, as there was a ton of slimy stuff on the print bed when it arrived. Used some isopropyl alcohol and a dish sponge to scrub it off, seems all fine now!

I had some issues with the Z-offset but got it good enough to where there is some first layer adhesion.

Model finished printing while I was drafting this post, I sprayed some contact cleaner onto the glass bed to take it off (is that bad?). There’s some stringing:

    Welcome to the club! It sounds like you know what to search for, so you’re off to a good start. If you haven’t found it already, Ellis’ print tuning guide will give you a good foundation for tuning your printer well.

    It looks like you have an Ultrabase bed, or at least something very similar. I had one on my i3 clone and it served me well for a number of years.

    As you discovered, prints will stick to it well if it’s clean. Dish soap and IPA (use the 90+% stuff) do a decent job of cleaning it. Windex also works well for keeping it fresh. Prints will easily release after the bed is cool, especially after the bed gets some miles on it. I’m betting the prior owner either had trouble with their first layer sticking or releasing - glue sticks are used by some for both scenarios. Proper first layer squish, a slow first layer, a clean bed, and a cool bed are all it really takes unless you’re printing something like ABS/ASA and then your first step should probably be an enclosure, not an adhesion promoter.

    I have that exact printer, and it’s an absolute champ.

    One tip that might sound stupidly obvious, but when the printing is done, let the bed cool down fully before you try to remove the print. 99% of the time, you’ll hear an audible ‘pop’ as the print detaches itself automatically. I’ve never had any need to ever use a scraper on it.
