First testprint with LokBuild http://www.lokbuild.com/
Got this when it was a Kickstarter https://www.kickstarter.com/projects/steelmans/lokbuild-3d-print-build-surface
I ordered the 203 x 203 mm (8")
I printed just a simple 170mm circle made with Tinkercad to test the outer limits.
Tested with cheap PLA (jupiter series)
Calibration points stay inside sticker area.
LokBuild recommends an unheated bed for PLA
And guess what, it sticks but comes off easily!
