Lights Out, Acorn DIY CNC manufacturing!

Uwe Mattern writes on the Acorn forum:

"sorry no problems....my cheap little mill runs without problems, Acorn and 4.99 beta software.

16h shift with 6000rpm, only short stops for changing work-pieces and still running perfectly

Will not get higher than 45°C, original only build for 2250 rpm

Can not complain about reliability with Acorn running short vector 4 Axis stuff day in day out 😉

So here it is, the 1st successful tool change. I still need to align it perfectly and get rid of some shims but I don't care, I'm still calling it a success, and I'm excited to get it filled up with tools, finally 🙂 .
The ATC build is running on a stepper pulse gen board (ebay), through the stepper driver, through a 100/1 harmonic drive GB (long story).
Now onto the 4th axis, harmonic drive again with a teknic SDSK to match the rest of the axis's.
Hopefully the below link works this time.............. I was excited just a little bit 🙂 ."
