Hi Jon, Well lets just say the only thing that I am sure about is the drive is under-damped. ;) Tuning is proving to be insanely difficult for me, I guess mostly because I don't really have much of a clue what I am doing. It is also kind of scary because if I turn a POT on the Gecko just a tad in the wrong way the drive violently rattles the whole table. When it was just the Gecko, that was something I had a grip on.

This gantry is probably close to 200 pounds, and I just don't know how fast I can expect to be able to accelerate it. Does gearing a drive help with this? I seems in my mind it should.

If it is a G320X there are internal DIP switches that can be used to reduce the torque gain which might help with stability. Do your encoders have selectable resolution? A lower resolution might also help tame the excessive response. Hi Steve, Thanks for the suggestions! But it is an older G320, and I currently have a fixed resolution on the encoder which is 1024 CPR.

The system was a dog, for reasons I don't quite understand, maybe rotten compilers. I'm pretty sure they have been out of business for some time, but might be wise to check to see if there are copyrights or trademarks on a name, acronym or whatever before using it.
