Summary

Inspired by the adjustable Z-bed by brianvanh I wanted to have one which can be adjusted motorized controlled by the upgraded smoothieboard in the cutter.
The realized bed can move its surface up to 30mm below the lasers focus.
Beside the printed parts and some different M2 and M3 bolts and nuts there are the following parts necessary:

  • 4 x quadratic aluminum profile 15mm x 15mm x 2mm length 300mm
  • 4 x quadratic aluminum profile 15mm x 15mm x 2mm length 150mm
  • 1 x NEMA17 stepper motor 17HS4401
  • 4 x GT2 20 teeth timing pulley aluminum bore 8mm
  • 1 x GT2 20 teeth timing pulley aluminum bore 5mm
  • 3 x GT2 16 teeth idler aluminum bore 3mm
  • 1 x GT2 timing belt closed loop 6mm x 1140mm
  • 3 x M8 threaded rods 67mm
  • 1 x M8 threaded rod 85mm for handle (if wished, otherwise 67mm too)
  • 6 x M8 nuts (4 x if no handle is wished)
  • 4 x 608 ball bearings 8mm x 22mm x 7mm
  • 2 x micro switches 105126SPGJL5375
  • 1 piece of stretched metal (better a honeycomb plate) 220mm x 360mm made of steel
  • 8 x neodyme magnets round 15mm x 5mm
