Re: 555 timer circuit

Hi Tom,

Yes, I can see that you're able to change the steprate using the PLL's,
Nice use!

Do you have steppers on X and Y? If so, there are several controller
programs out there for free! If you're not familiar with CNC programs
yet, The jog commands allow you simple moves (usually with keys), or the
MDI (manual data input), can allow you to simply input the next point
you want your cutter to be at: "X1.5 Y1.5", IMO (from watching my oldest
son quickly pick it up), is an EASY way to do cuts! No diagram or
program to write! Now if we were to expand it by allowing angles to be
specified (how about circles), I think we'd have the start of a
"conversational" controller (Ron's working on one).

OTOH, as I've already discovered, having a little package that will
command motors is really handy!
