Description:

Shoot for the Moon!

The 3ft tall TALLCAT has a vertical build area of 640mm.

This is a Pyramid Repstrap made with all 1-Dimensional 90 degree cuts.

The 1X2 and 1X2 TALLCAT are RepRap class 3D-printers that can be built with access to only a drill-press and hand-saw. The parts for the entire system can be made with one-dimensional tools, straight cuts and common materials.

First Test:
607mm tall single-walled tube(40mm diameter).
Z-Step: 0.30mm
Print Time: 5hr40min

This machine is made by: mrkimrobotics.com

Design:

The TALLCAT turns its biggest weakness, long flexible rods, into a strength by using the flex to triangulate the frame into a pyramidal structure. The rods bend out of the way of the z-bearing blocks as they ascend from the inside of the pyramid to the outside. This makes full end-to-end travel possible even with a highly acute frame.


Improvements:

  • Eliminated frame spacers.
  • Eliminated 45mm M3 bolts.
  • Eliminated 25mm X-motor spacers.
  • No more asymmetrical countersinks.
  • Lower Table increases active Z-Travel.
  • X-Travel increased to 160mm.
  • Lighter X-Assembly.
  • Simple pinch belt clamp has easy tension adjust and requires no through holes in the belt.

New:

  • Vinyl shaft stops
  • Dual Pivoting footed vertex allows adjustable bearing block alignment.

Status:

  • The Y-Carriage version is working.
  • The stepper-driven conveyor-y-axis is physically sound but the control system is still being developed so it is experimental.

Y-Carriage Version:

This version uses traditional toothed timing belts and a one-piece Y-carriage design.
