Larger Heated Build Platform

Summary

This specification describes a heated build platform larger than the HBPv1.

Rationale

The HBv1 has two flaws addressed in this specification. The bolt heads protrude above the build surface, reducing the normal print area. The normal print area can be larger considering the interior of the CupCake CNC.

User stories

  • John would like to print Mendel parts. He needs to utilize most of the print bed, but the bolt heads are in the way.
  • Jessica wants to print objects that extend to or beyond the normal build area.

Assumptions

  • A larger print area is useful.
  • The Cupcake CNC can accommodate a larger print bed.

Design

  • Tapered bolts should be recessed in the heat spreader plate.
  • Determine the maximum print area for the Cupcake CNC. Maximize the print bed accordingly.
