Guys...
I have for sale my last CNC machine, and its a nice one. Designed and built for guitar makers, it has features beyond what you would normally find in even a high end consumer machine.

A full description and pricing is in the attached PDF.

If you really want a chuckle, you should know that before the spindle started the system played the "ooh ah, ooh ah, ooh ah" (sound7) from the M$ 3D Pinball Space Cadets video game for 2 seconds. P.S.: It was hard coded and non-removable.

Shameless marketing bump

I have emailed the "regular" and inverse time mode imperial versions to you. You will need to make the swap to metric

Price reduced to $11,500

I have not seen it work, the CNC PC that came with it was dead so I decided to switch it to Centroid to get it to work. The previous owner used it for a few years and then got stored away for 8+ years and then donated it to a church that just wanted to get rid of it.
I'll look into the pinouts ...

I am assuming that your control failed. That is usually the result of a failure in the Testra "box" (shown circled below). You need to remove the Testra and wire your motors, limit switches and estop into the Acorn to replace it.

I have received a number of questions regarding this machine. Answers below:

Spindle is 18K RPM, Air Cooled, Collets from 1.5mm to 12mm metric and 1/8 to 1/2 imperial

Spindle has been trammed with an Edge Tram Guage on a machined plate: https://www.edgetechnologyproducts.com/pro-tram-system-01-000 ...

Yes, it's not a bad idea to use multiple power supplies, but you must connect the commons together.
