enough "sensible", let's try "more aggressively compact" ... and 3d printing

A project log for "Desk Accessory" CNC Milling Machine

Lots of "Desktop CNC" machines can fit on a desktop. But do they fit _on_your_desk_? Like, between the stapler & paper tray?

Trying something(s) different here:

It's still work in progress, but seems like it might work out ok.

The mechanics are a lot like #Minamil: a minimal CNC mill. And friends., but different. Re-design for 3d printing the mechanical parts is not just trivially different from design for 2d laser cut parts. I don't know yet whether to expand that project or start a new project.

I was actually, planning to build the laser cut version, but using printed parts.  Then I see this post and you've, not only, redesigned it for 3d printed parts, but also made it bigger, and more compact.   Longer 6mm rods I have.  As for the longer motor+screw unit, do you mean the one that has an 80mm screw?

Motors: yeah. 80mm stroke (screw is ~90mm). With the same white plastic slider -- not the fancy flavor with a brass slider on bearings.

It looks pretty good to me.  Okay, what do I need to order and print to make one?

I appreciate your interest and would like to help you make one. The unit in that video is a very rough draft and probably not what you want. Unless you're very anxious to get started asap. I'm working on it and hope to have more to show & share soon.

If you want a head start on parts: the hardware is mostly similar to the laser cut version, which you're already following. This one uses the longer version of the motor+screw unit that you'll likely find if you look up the shorter unit used in that version, and 120mm instead of 100mm rods for X&Y. No short rod option for Z.

Hey Jamie, "soon" is starting to happen.

Check out #Minamil 3dp: another minimal CNC mill and the logs and

"Public chat" (big yellow button) is open for the project.
