looking for a good 3d printer

[Desertboy]

I print onto Kapton tape or straight on to a mirror with ABS juice (Acetone and ABS dissolved together). Since I rebuilt my printer and now it's level I rarely have one that doesn't stick to the bed. At least for me 99% of sticking to bed problems were to do with the nozzle being too high or too low.

If I got another one whatever I bought/built I would make sure the Z axis has a contactless solution for setting the Z height. Inductive probe works well as long as you have an aluminium heated bed I use an 8mm probe and it will sense the aluminium bed through the mirror glass which is nice. Optical end stops are good too and hall effect switches. I found microswitchs unreliable for the Z axis.

Never ever use stainless for a print bed stainless has very poor heat conductivity. Tooling aluminium is the best choice for a bed because it's light and has excellent heat conductivity that's why they make heat sinks out of it. The super flat is just a bonus.
