I didn't see anything on the Acorn that suggests it supports a Charge Pump to
protect the system if the PC goes bye-bye.
For that matter, small survey question here, how many people running LinuxCNC
are actually using a Charge Pump for safety?

I was for a while but am not now. At the time I was cutting out blanket
chest parts in Green & Green
style joinery, i had 2 rigged to control the board locator and the
vacuum on my carving jig, which I
had to move out of the tool path once the board was clamped. The 2nd one
started the bucket vac
to clean up the mahogany swarf as the tool moved. I sure wouldn't call
that pc byby insurance...
Just shade tree engineering. :)
It is a decent, one pin control solution if 500 millisecond response
time can be tolerated.
