I'm working on using an ATtiny to watch EMC2's charge pump. The plan is
to have a count down that gets reset by a charge pump edge. If the
counter reaches 0, then an alarm pin gets set. The counter reset value
determines how long the charge pump has to do a reset. I can write code

I like the idea of a dip switch or solder bridges if one doesn't plan on
changing the setting alot and wants to save the cost of the dip switch.
while the pot would be easy to adjust, it's less precise than a truth table
of the dip/bridge positions and the resultant reset timer.

Once a serial link to the EMC2 host exists, is it possible to resist the
temptation to put in a $3 - $4 ATmega, to limit the risk of running out
of code space, once the ancilliary functions stick their grinning faces

Just as a random data point in all this, I have a little 7x toy lathe
currently running with Mach2 that I'm getting ready to switch over to EMC.
It homes using a single snap-action microswitch, the kind with no lever. I
don't know if this is different from EMC, but Mach homes by backing in until
