Upgrade: 25x material removal rate (forum.guncadindex.com)

I posted a while back making some small parts in 17-4ph stainless on a $500 desktop CNC.

The removal rate was slow but acceptable. However, I had some mic6 offcuts laying around for another project, so I used the machine to upgrade itself.

20mm mic6 side plates, nearly doubled working z height.

1.5kw vfd spindle replaced the old 300w dc motor.

In aluminum, my material removal rate is now 25 times what it was stock, and no more chatter. Should speed up my projects quite a bit, and any other upgrades seem moot at this point. Absolutely incredible to hear this thing sing with just a new spindle and some scrap aluminum.

That's super informative! Thanks so much for explaining in such depth.

    For sure, I want to push this community to utilize cheap home machining because it pushes the envelope wayyy further in making gun control laws a futile effort, and opens up so many cool project opportunities. Especially with this machine design, it is very defensible as it is open source and easy to diy from the ground up as long as your extrusions are cut square and you can procure the parts.

    I have quite a few projects lined up to accomplish some big goals, the slide I’m making now is just a fun one to get started.
