DIY 3-Axis CNC Milling machine Part 5: Up And Running

The long overdue video of the completed CNC Mill is finally here! Some last minute changes have been made and a lot of peripherals have been added to the mill. The project is finally in a state where I can fully focus on actually machining parts with the mill.

Have been waiting for this video. Cool to see the CNC making chips, well done!

Great to hear, thank you!

Nice man!

Thank you!

I just watched your whole 5 part series to date. Very nice design, build, and video production. I didn't see you mention how you trammed the Z axis. Can you show/discuss that? Also, are you a mechanical engineer? Thanks.

[@tw2ka644]

Thank you I appreciate it! I trammed the Z-axis by placing a 90 degree angle gauge on a vise in a way that one side was facing up. I first zeroed the gauge with a dial indicator so one side was in line with the Y-axis and then attached a dial indicator to spindle and moved Z up and down dialing against the gauge. This way I found the tilt on the YZ-plane. Next I did the same thing but zeroed the gauge on the X-axis and then dialed the Z movement on the XZ plane. I corrected the tilt error of the Z-axis column with little metal shims. Then I went ahead and trammed the spindle by placing a long end mill on the collet. I again moved the Z-axis up and down and measured the angular error from the front and side and corrected the spindle. Hope you understood this and yes, I am a mechanical engineer who specialized in automation and robotics!

@@tw2ka644 Great, yes I understood. The shim is what I was after. I didn't know if you went with that or a metal filled epoxy or some other method. I'm an ME also, but most of my time has been designing plastic parts for injection molding. Here is my cnc design playlist if you are interested. I'm still in CAD, slow going, ha ha. th-cam.com/play/PL_e9tdItiJstrB6WyruH1jfdonHBbIJdD.html

What is the size milling vise?

[@tw2ka644]

Outside measures 300x110x80mm and vise jaws open up 120mm.

how much work piece weight it can hold

[@tw2ka644]

I think the wight doesn't matter too much. It's more of a size question. The movements are X300 Y200 Z200 mm.
