Here is the latest update on my project. I have made some improvements to the ATC module cover.

First problem, and I don't even have the main body of the machine home yet!

As I said the stepper motors are really nice disc armature ESCAP motors but they are connected to the 16mm ball screws...

The whole point of an Impact Driver Mechanism is that it isn't reliant on motor torque, it releases the drive in response to pre-settable torque demand, allowing the spindle to accelerate, it then...

OK, here we go again. You may have seen my last rebuild of a Boxford VMC260 (https://www.mycncuk.com/threads/15971-Boxford-260-VMC-rebuild). I thought that would be my final one, but while browsing...

Suitable BOBs do make life far easier, especially with the micro sub-d connectors used.

The 'Ethernet' control is more likely to be EtherCAT, CAN, or ModBus.

ModBus is generally too slow for...

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 think I fitted a similar drive for someone last year.
They're all a much of a muchness. I suspect there's limited actual manufacturers of the drives, and they're mostly relabelled/cloned.

"I use Vectric Aspire and CorelDraw for line drawing. Both are relatively easy for hobbyist use, especially for 2D designs. Of course, Aspire and CorelDraw aren't AutoCAD or Fusion, but I've created...

I used TI chips that do current monitoring for a Nema23 3A cnc long ago. They ramp the voltage high but limit the current. This allows higher acceleration.

I'm amazed how reliable they are on a...

I figured it out.
After you do "fit text to path", you can also adjust each letter individually for the spacing (kern) or vertical offset. This is good so letters don't touch each other or the...

Ray,

Taking into consideration all of your responses to all of the threads you have posted, my conclusion is this;

You want to make guitars so just buy a cnc machine that is already built, be...

Select "reply", then "go advanced", then "manage attachments". Then "add files" to upload files. Then drag the ones you want into the box and you are nearly there. "Add files inline" inserts the...

It would appear you're referring to this video:

In which case, Mercury CNC appears to be a commercial entity:

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!

Hope you will have a better new year and hopefully your new nee holds up.
Best wishes Clive

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've not had any response from the gentleman Lee.

I'm not in his neck of the woods but I can probably do what he needs.

It doesn't look like he's logged in since he made the post

Another possibility is to get a product shipped to a forwarding company in the EU or some other destination where the alleged exclusivity doesn't apply.

I recently bought a couple of ArcCaptain...

If you want to avoid Mach, then I'd doubt that there is anything available ready to go, and something custom built by somebody else is likely to cost more than $600.

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