The Axis X, Y and Z

A project log for The Omni multi-machine

Laser cuts, routes, plots, engraves and makes vinyl stencils and more for makers ,crafters and builders.

The prototype uses axis made from 3 D printed parts and off the shelf components. I used the pancake type steppers on these but have designed mounts for other footprints. The printed parts are designed to self align, are fast printing and very rigid and stable. Here are the major parts for each axis:

After many designs the axis have never been easier to make. Here are things slipped together and ready for final assembly.

Not sure yet what the final design will be yet. This years contest leans heavily toward mass manufacture.

Yeah..  The whole mass manufacture mindset part of this year's HAD prize I am not really onboard with. 

I think limiting yourself to that mindset could be significantly detrimental to the early stages of development of projects without a certain outcome.  This mindset will benefit organizations and companies with full product plans, but a lot of good ideas will ultimately end up being abandoned simply because they didn't seem mainstream enough at this time.

What project that has changed any significant existing paradigm in the past has *ever* had a certain outcome?

I started two of my most interesting projects this year with absolutely no goal whatsoever of 'selling' them and they have both evolved to become something worth pursuing and releasing to the world.  Neither is really marketable as a product as there is nothing to sell.  Both are Open Source and fully 3D printable.

Meanwhile my actual product entry is still waiting on parts.

This is not a criticism of you or your project.  You are doing what I'm still about a year out from.  :)

It is a criticism of where I think HAD is heading this year, and you touched that nerve.

Move along...

I thank you for your comment..I am in COMPLETE agreement with every word. Perhaps I should not be poking the snake with this project(mainly my other project :)) but I think the contest was always about open source and do-it-yourself. I certainly don't have the resources to mass manufacture anything nor do I have a desire to do so.

On another note I really like your gearbox project. The dream for me there would be to be able to mount that on top of a standard nema 17 stepper with a 5mm shaft. Would make a killer rotary table axis. I am unable to use you DXF cut files however as I am an STL moron who can't seem to convert those type files and make them work or import them into my cad. Too embarrassed to ask anyplace but here(nobody is gonna read this ever)

You might do well making your gearset fir a number of motors though.

What format do you need?  OpenSCAD can create like 10 different ones for export, and the shaft diameter and such is just a variable in that script.

Stl is the only thing I can use. I use free software that's outdated and it only creates and saves in STL. My printer will only take STL format also. As long as I make it myself its all good but other peoples stuff that is not STL I am just outta luck.
