DemonDeltaTube - Delta Printer in an acrylic tube

DemonDeltaTube Printer

Update 08-03-2018 Added a carriage suitable for anti-backlash nuts. It is 1mm shorter as the antibacklash nuts springs take up a small amount of space and this affects the leadscrew to nut alignment.

This is a repository of the parts for this machine if you want to emulate it. Please attribute.

I have added most of the parts for this machine, extruder is up to you depending on what you want to fit. Recommend ABS/PETG as it does get quite hot inside.

Effector -

Update 11-02-18 Added hole in effector for hotend wiring which was useful as I was assembling it.

Integrates Precision Piezo - Piezo20 nozzle contact sensor (requires a suitable amplifier such as https://www.precisionpiezo.co.uk/product-page/copy-of-piezo-signal-pcb-kit-version) to function, and a drilled 20mm piezo disc, some modification to the endstop cable headers is required currently. Designed for genuine e3d v6 (with integrated miniature bowden coupler), recesses in the side for bonding 30mm blower fans (https://www.precisionpiezo.co.uk/product-page/sunon-blower-radial-fan-5v) space to attach a 30x30x10 fan from the e3d kit, designed to work on the 55mm spacing magball system (Haydn Huntley https://groups.google.com/forum/#!msg/deltabot/485cfVFrFFU/feT5lm8WfIwJ). Assemble piezo sensor as per documentation at https://www.precisionpiezo.co.uk/documents

Make sure magarms are arranged with negative and positive poles at the effector end on each pair of arms, so the arms attract each other when disconnected from the effector. This balances the magnetic fields around the effector otherwise they stop the fans from spinning properly.
