4" Vertex Rotary Table CNC conversion

For this particular application the 24v limit shouldn't be a problem. I run mine using 19v laptop PSU's, there's no real need to go above that.

Like kwackers mine is 19v laptop PSU which below the 24v the driver is rated at,
I left mine running on continuous over night & it's still o/k. But may be it's starting & stopping the controller which could cause problems.

I doubt starting and stopping would have any impact - these things are switching on and off very quickly anyway, that's basically how they work.
You'd actually stress it more by leaving it powered but stopped than by continually moving.

Coming a bit late to the PCB etching party: I've read tracing paper is a happy medium between the opacity of paper, and the expense of transparencies.
