While I progress with the boring wiring bits on my milling machine project in the background; something a bit different in this heat . . .

For those following along here is the next installment, getting the control boxes and DRO readout fitted.

Thank you to JLCCNC machining services for machining the main parts of this build. See the...

Time to move onto the main head assembly and tear down the drill press to recover the column. Starting to take shape now.
A big thank you to JLCCNC for machining the main parts of this project. ...

Does it vary with speed? Steppers can emit squealing noises at different speeds (usually low speeds) and this travels down the ballscrew and can sound like it is coming from the bearings. Steppers...

I've installed quite a few of these Huanyang VFDs on different machines in my workshop and all have worked for years except one a long time ago which went bang a few seconds after the first switch...

Time to get this project started . . .

Thanks m_c. From what I can tell they should be more than powerful enough for what I need. I've seen them used on a 150kg bridgeport knee (usually via a pulley of 3:1 or similar) so my 40kg head...

I decided to strip down the rear end of this spindle to get access to the pulley. It took longer than expected!

For reasons that will soon become apparent I was searching for a milling machine spindle and came across this interesting item. BT30-ER20 tool holder, air powered draw bar for tool changing, HTD5...

Time to fix it properly . . . well my way anyway

It's been broken for many years but it should be an easy fix . . .

Thanks for all you do on this forum. Have a great Christmas and a speedy recovery!

Finally finished. We needed to strip down some of the machine to route the wiring, then it was time to upload all the information to GitHub.

I finally get the controller installed . . . after more tinkering!

I've been wanting to do this project for a while. I wondered if it would be possible to build a spindle monitor to check if it has stalled out and then e-stop. Hopefully this would stop it breaking...

It's working! Had a few issues in this one, but I think we got there:

Thanks Lee.

Back to the OP - it was a long time ago but I think I used this VFD on my CNC machine, or something very similar.

So if you know the 2.2 kW motor specs you can set up PD003 - PD008...

OK so it is a sort of pick and place machine with no real loads at the end effector (dispenser end)? And the positioning errors there when you just jog it about with no load on the effector?

I...

XYZ axis complete!

Overall I’m still happy with it. It started to cut off square but this was fixed by retightening the main pivot bolt for the arm. 400 Watts is fine even on very large pieces. It has never...

X axis gantry, cheap linear rails quick look, new Z axis touch off (again!) and Y axis movement.

Thanks. To be honest making the videos helps me stay on track and finish them!

OK, I finally found a well priced and well featured plasma cutter. Here we go again on another CNC project!

This is not the question you asked but for extra security (just as a general step) you can check the resistance across each winding pair before connecting to the driver. Should get a few Ohms across...

Hi,
I'm not fully committed to this, just looking into it for now, but does anyone know of a low cost plasma cutting machine suitable to use with a CNC machine. I think HF start is too risky -...
