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.pic.twitter.com/bILFcaWSMC

Well, no harm done except for one teeny scratch on build plate, which won't matter since I plan to tape it up now anyway.

I *think* the most likely reason I'm getting extreme sticking while most people seem to suffer from insufficient sticking is that my nozzle might be too close to the print bed, making my bottom layers too dense. See this threadhttps://twitter.com/divalbanerjee/status/1297301260035674112 …

The way to test this would be to run an experiment at different bed levels with the same print, and measure the force needed to get it off, but I don't want to... direct on plate is too temperamental for my tastes. Gonna try taped up approach next.

careful with blue tape, sometimes the first layer doesn't grip the tape very well, just keep watch over it for the first few layers there's really nothing better than tiny knift + spatula combo

Is this where heated plates come into play?

Also I’ve only briefly played with TinkerCAD but it was cool

i like to just use one strip of blue tape on a corner, basically to give myself somewhere i can then easily work my spatula into. but i also use rafts so the slight un-evenness isnt an issue

Oh, this is very clever... I might try that. Why do you prefer to build directly on the plate though, instead of taping it all up?

What bed temp and extruder temp were you running? Bed temp especially has a big effect on how much a print sticks. Also slicer programs have options to add a skirt around the edge or "raft" underneath the print which can make it easier to remove

You might try laying the first layer down at a reduced temperature...there is gcode that can do this...alternatively contact-paper as a bed-coating worked for me...basically 'large tape'. Spray with hairspray...then peel off.

This tweet is from august. I figured out my sticking problems.
