Robust Kossel

This project focuses on improving the reliability, print quality and speed of a Revision A Folgetech Kossel.

Goals
The main goals of this project are:
 * Creating an enclosure for the print volume to reduce warping when printing large ABS parts.
 * Modifying the effector to allow Z probing using the print nozzle as the probe to reduce the amount of error when measuring the offsets between where the printer thinks the bed is and where the bed actually is.
 * Converting the rails to rollers to increase the maximum print height and reduce the rolling resistance of the carriage.
 * Converting the stock direct drive extruder to a geared wades extruder to allow more a consistent feed of the filament into the hot end and shortening the bowden tube to give more precise retracts.

Heated Enclosure
The heated enclosure will be made from sheets of perspex, as long as the temperature of the inside the volume is not too high the enclosure be robust enough to keep the hot air inside. The enclosure will be heated by the hot end and heated bed of the 3D printer.

The enclosure will also have to allow the extruder of the printer to be mounted and pass the bowden tube through the sheet.

Currently I am designing a simplified mockup of the printer to give accurate measurements when designing the sheets of perspex.

Probless Effector
The effector is the part that the tool mounts on
