3d printing is a world of superstition and old wives' tales. Tricks I read/was recommended for getting stuck-on prints off the build plate: 1. Wait for it to cool so differential contraction breaks the bond 2. Take it off hot (while it's still soft at the bottom?) 3. Ice it...

Printing my first self-designed part 😬 Did it with OnShspe+Cura... haven’t used CAD software since 1996, which was ancient version of ProEngineer. Things have really advanced a lot. Browser+cloud-basedwith version control and all sorts of other crap.

4. Swab isopropyl alcohol around edges 5. No isoprop alcohol doesn't work and can't dissolve PLA 6. Try water 7. Regular water won't work, try de-ionized 8. Put tape on plate to prevent this 9. No tape needed 10. Use blue tape 11. Blue tape can't be used on heated bed...

12. Yes blue tape can be used, but only for lower temperatures 13. Use kapton tape 14. Don't use kapton tape, it's a bitch to get off later 15. Take the plate off and freeze it 16. Heat up the plate to above build temp to melt bottom layer 17. Try flossing around bottom

18. Lower the plate a bit 19. Use a raft (thin, coarse base layer added to design) 20. No need for a raft... My additions to the lore: 21. Drill a hole from the side to shove a rod in to lever off (didn't work for me due to low-density draft print, but might work for others)

22. Use boxcutter blade to shove under model and prise it up just enough to shove in a thicker wedge like a screwdriver or thin spatula. This is what finally did it. I must have tried half these methods along the way (couldn't freeze the plate since the wires are soldered on)

There are more systematic approaches to bed leveling.... but often people just get away with the paper under the nozzle thing(imo this gets you in the right ballpark, but needs more precision). I should write a guide on how to get those remaining settings dialed in

3D printing is in the “laser printer from the 60”s territory where it’s useful enough to be used wisely but is still built on a pile of process tricks. Not mature enough to be bundled for $30 including plastic filament from Epson

3D printers aren't standardised enough that a small number of approaches work for everything. What I did to work around this is to buy build plates. Used one with my printrbot, and also with the Flashforge Dreamer at work, and it's so much easier to get prints off the base.
