Two Color Inlay w/ 1 Extruder Small Letter Test Print (No MMU)

Maybe you've seen CHEP's video for printing a 2 color inlay using Z Hop and weren't sure how to do it with a Prusa (since if you follow this method, the Prusa will try to ABL while half the print is still on the bed) or you're trying to dial in printing in small letters. This should help!

Printer Settings

  • Extruders: 2 (or more for more colors)

  • Lift z enforcement: Enforce on first layer

  • Tool change G-code: M600
