Hi again Mark:
If you're having a hard time deciding, it may be a good time to reach out to a tech rep from each of the companies.
I don't know who the Sodick guy is in your neighbourhood, but the Makino guy to talk to is Brian Pfluger who participates on this forum from time to time.
He's very knowledgeable and seems to be a really decent guy too, willing to answer your questions objectively.
They are both great brands; easily capable of doing pretty much anything you care to throw at them.
Be aware also, that setting up and programming for a sinker is pretty simple compared to setting up and programming for a wire until you really get into the weeds for a special, super complicated need.
So I wouldn't be intimidated by the thought of running a new control regardless which brand you choose.
If you have the coin to spend and if your burns are mostly tiny (like 0.015" diameter 0.010" long to +/- 0.0001") the Makino will not knock up against any precision or spark generator limitations like a more conventional machine will.
If your burns are more like 0.050" diameter and 0.050" long (or bigger), and you can live with +/-0.0003" or so, you could pick almost anything reputable and it would be fine.
I'd reach out to Brian and let him make his case for a Makino...let him walk you through it all and justify his preference.
Then talk to a Sodick guy and let him have his say too.
By the time you're done, you will have decided, and regardless which one you pick, you won't have made a bad decision unless your need is truly unique.
