History

  • The System was introduced during our KickStarter campaign, and came with a 23" tall enclosure.

  • The System 30M was introduced in 2013, and came with a change to all metric fasteners and custom extrusions, and a single (vs double) front door.
  • The System 30M v2 was introduced in 2021, and comes with better motors with closed-loop feedback and quieter operation. CE marked units are available upon request.
