4.0 VAAPR Bed​

VAAPR Installation​

  • The VAAPR bed is slightly smaller in area than the Prusa Mini PEI sheet. When installing the VAAPR bed, center the VAAPR bed over the print area square on the Prusa Mini PEI Sheet.

Purge Line Modification​

  • The default purge line created by PrusaSlicer prints slightly outside of the print area, so with the VAAPR bed installed, it will try to purge outside the VAAPR bed area. To solve this issue, you can either move the purge line inward (+Y) by 5mm, or delete the purge line entirely in the machine start gcode.
