At each stage of the script, your Duplicator 3 will ask you to test the platform height by sliding a piece of paper
between the platform and nozzle. Your Accessory Box included a business card from Wanhao Support. It's
about .12 mm thick, and should work great. If you haven't got the Support card on hand, a sticky note works
well, too.
When you're done, The Duplicator 3 will ask you if the nozzle height is OK. 3.5
Use the Support card to test the platform height one last time. If the card can move up and down underneath
the nozzle, your platform is too low; select “Let’s try again.” If it can slide around a little bit, you’re good to go.
If your platform is too low, your prints might not stick to the surface, and if it's too high, the nozzles could tear
the Kapton tape on the platform surface. If you're having trouble, or if you just need to level your platform
again, you can always get back to the leveling script in the menu by going to Utilities->Level Build Plate
