OpenBuilds OX CNC Machine

Openbuild OX CNC from frame kit 750x750 size

Putting it together was like getting my Lego Techic Car 853 back in 1977, (best ever Christmas present).
All the parts I needed and a very clear instruction manual, kind of unique for me.

That was the easy and quick part.


I bought a 24v power supply and one Stepper at the same time as had others left over.
The Controller was a cheap eBay purchase with individual stepper drivers. These were configured, wired up and fitted into a 1U server case.

Other parts to finish were, Cable Drag Chain, 4 Core CY Flex Cable, Aviation connectors, Stop Button, micro switches, Kress Milling Motor.
I really like Mach3 and so bought the full version of this CNC Software.

I made a break out box for the limit and other switches back to a 9pin connector and lead, this gives a bit more flexibility for later upgrades like probes. Everyone likes probes.

Stop Box was laser cut and plugs into the break-out above.


The bed is MDF, 6mm hole through, 8mm counter sunk and 12mm routed to fit the T-nuts, 80 of these should be enough.


Hold downs I made from acrylic, snail spirals in a few sizes. They can hold any shape and are such a low profile don't get in the way, you can even double them up for weird size material.


Most of the time was spent making a new Kress motor mount with vacuum attachment. Hell it makes a mess without one.
This I wanted to be of transparent acrylic. It snaps together with hard drive magnets I embedded, this also worked for the draft excluder I bent into shape as this also snapped on nicely and wouldn't hurt if got caught on a component as it's not physically attached.


The Video explains it better.

Working and not making a mess!!


So what can it do? Well stuff like this:



And a load of other stuff I've not done yet.
