Tom,

Yes, I meant SnapAmp. Current should not be a problem - my servos are rated at 8.5A continuous, 38A peak, and the only time I probably hit the Gecko max is when I run into a vise or clamp.... The extra I/O would sure be nice.

The Gecko method of tuning has you monitor the actual internal analog error signal with an o'scope. It actually works better than watching the encoder on the KFlop (which I have done), but getting to the test point is hard - it's just a 1mm pad on the PCB, so you have to have good access to be able to do it, and it's real easy to blow something up if you're not careful. In my system, it's a LOT of trouble to get to the test points, as the Geckos are all buried in a big E-Box that's jammed packed with ALL the electronics for the mill.

Regards,
Ray L.

Certainly, from a wiring, packaging and space standpoint, it would be a significant improvement. The software programmability of the servo parameters would also be really nice (right now, the Gecko adjustments are very hard to get to, and it's near impossible to monitor the error signal in-situ).
