In my previous post I explained how I acquired an Ender 3 v1, v2, and v3 over the course of a week after not owning any 3d printers, well, it's been a couple more weeks and I got a couple more printers. I spent several days trying to troubleshoot the Nebula pad that came on my v3, finally got it unbricked only to have it stick in a sort of boot loop so I gave up, I was going to just buy a screen for $40 but I got a whole nother machine for $70 which is good because I ended up replacing the screen and main board and now I have the rest for parts (the first one has several mods so fixing it rather than using it for parts made sense to me).

I fixed the v2 that I got out of the dump by adjusting the bed and replacing the stepper on the x axis and then gave that one and the v1 to my oldest daughter.

Deciding that I need to unlock the wonders of multi color printing I bought a FlashForge AD5X for $160 that had a bunch of filament caught in the bowden tubes and extruder. After fixing that I gave it a wash and tried printing a benchy but I can't get it to stick. I'm going to play with some settings tonight and see if I can get this one printing as consistently as the Ender 3 v3. I saw glue mentioned a couple of times, would a glue stick do or does it need to be something special?

Also, what type of grease do you all recommend for your machines?
