(25 May update: side options)
This very low cost linear slide design does most of the work of my #Minamil project - a “minimal CNC mill”. I hope this rendition of a single isolated unit will serve two purposes:
- Share this idea as a concrete, ready-to-use example
- Isolate and simplify the hard part of describing how to make a Minamil-like machine
Maybe you can use this to reduce the entry cost of some other project!

If you want to try one of these (or three) for yourself, check out detailed build instructions over at Instructables.
The CAD model is configurable for:
- material thickness
- handwheel or stepper drive
- driving/driven side
- application option, selectable for each side:
A couple of example configurations:
handwheel drive • heavy load configuration
stepper motor drive • fixed point-of-action configuration
The moving load/fixed PoI distinction illustrated:
Where this comes from, and i̶s̶ slowly g̶e̶t̶t̶i̶n̶g̶ got back to:
But HaD.io projects can include instructions...
Why send traffic elsewhere instead of writing instructions here in sunny HaD? Because the longish 'ible was a mess until it was done and I didn't find how to save unpublished instructions-in-progress here.
