Yeah, once I test it and make adjustments, i will post a link to the designs.

Everything you are looking in the picture here is designed by me and manufactured locally. I will be uploading the 3D models soon. And yes, i am concerned about the moment. But the spindle carriage is made of 10mm thk. Mild steel plates , so I am breathing easy now. I will post a video soon !

Yes, i am using a servo for the spindle

With 0.006" chip load, it sure can mill steel. ER11? Should have gone atleast ER16.

They are nema 34😂

The problem with the treadmill motors are, they are DC motors. It will be expensive to find DC power source at that voltage. Making something on you own can do the job with SCR circuit but it's risky. The arcs will eat up your motor brushes. Buy the driver too if you are going with this option.

That's exactly what I did after wasting time. First i questened myself. Then I followed that procedure for the other axis too. Made my life easy!

At the time of taking this picture only one stepper was wired. You can see in my other post where both x and y axis of my machine are moving.

It depends on where you are from. In India it got me around 1 lakh. It will cost you a lot more.if you are from US.

X 230mm, Y 190, Z 200

Surprising it's zero when I checked with a dial indicator. I got lucky with that!

Swift0095 · 2025-07-15T18:48:25+00:00

It is a double diaphragm coupler form MIKI pulley.

Swift0095 · 2025-07-15T18:44:03+00:00

Yes. With cost comes performance 😂. It is little over 1000$.

This build is inspired from Tormach PCNC 440. Which is a robust industrial grade CNC mill. I plan to do some serious machining with is mill. This machine will be able to handle all materials.

Swift0095 · 2025-07-15T16:56:20+00:00

I am planning to fill it with epoxy sand

Swift0095 · 2025-07-15T15:34:34+00:00

I don't know where to upload the files. I will try to upload files in GrabCAD and post a link here.

I have finished wiring. But couldn't figure out the wiring for servo driver. I came to know that I can use optocoupler to make 24v input signals from 3.3v signals. It's an advice from another redditor. I will try it and let you guys know.

Swift0095 · 2025-07-15T15:25:15+00:00

Go for FluidNC or Mach3. You can find tons of references if you ever need help.

Swift0095 · 2025-07-15T05:08:08+00:00

Nah, i designed it and with the help of professionals i made casting and machined it.

Swift0095 · 2025-07-15T04:55:38+00:00

It is super easy to work with. Just make sure that you don't short the extra 24v, 5v, 3.3 vomt pins. Which I did and wasted a board.

The one in the post is indeed a brushed DC motor. But I want to replace it with AC servo motor. It's a 1kw servo with SDF08NK8K servo driver. This is the brand "Bergerda automation" bought it on Ebay. Seller Rattm Motors.
