OpenBuilds limit switch kit for MAX METAL frame

[bvandiepenbos]

I found this on OpenBuilds. It makes a easy way to mount the limit switches on my MAX METAL Frames.

Micro Limit Switch Kit with Mounting Plate

Way easier than how I did it. Drilled & taped M3 holes. Hard to get holes in just the right location and spaced to fit switch holes. And spaced switch away from extrusion with 6-32 nuts.

You could also print brackets, somewhere on seemecnc forum are the .stl files shared by ccavanaugh

Nice,

Side note: Would these work for the Mill?

Or are these too small?

that "C-Beam" extrusion is really nice. I Don't think it would really work well for mill.
I have one that I can put together and bring it to next meeting.
It should make a great Z-stage for my resin printer build.

Actually, I am thinking the Hive would be better off leaving the mini mill manual and perhaps adding a DRO to make it more useful.

A great value at $565.00 including nema 23 motors
Then instead of putting money into cnc conversion of mini-mill buy a "C-Beam Machine" kit for the Hive to have capability of machining aluminum plates. I doubt we would have much more invested overall.
C-Machine has larger cut area than mini mill.
I appears to cut aluminum plate reasonably well by watching videos.
I have a 3 axis CNC board I would donate to the Hive for the C-Machine.
Other than a PSU that is about all that is needed, I think.

It may look like another OKO or X-Carve Machine, however the big difference is lead screw drive vs. belt drive. Belts will never have the rigidity to cut metal.

What is a DRO?

Digital Read-Out

Lets discuss that Thursday. Wish we had found open builds one before buying the mill.

We knew about the OpenBuilds machine before. makerhive.proboards.com/thread/1408/new-openbuilds It's basically a beefy ShapeOko.

I'd still vote to convert the new mill. It's a lot heavier and capable of doing more serious work in the end.

Oh yes I remember looking at it now. I have to agree, I think the mill will be sturdier, faster. Just not as big a cutting area.
But lets weigh the pros and cons this week.

This is relevant, too.
