encoder question for G320

[CNC Darren]

Hi all,
Well after waiting what seems like forever for Rutex to get on the ball with thier 2000 series drive gecko's are looking better all the time. I have 500cpr encoders for my new router that I am in the process of building and have seriously started thinking about using G320's. My question is I recall hearing that people that had higher count encoders had problems with them faulting due to the limited 128 count servo lock. Did anyone ever fine a solution for this? I'm about to the point of ordering the drives and am wondering if I should just got with gecko's. Also it seems the Gecko customer service is about as best as someone can get!

Darren,
When I started my CNC (V1.0), I was using 1000 line encoders (4000 quadrature) and the only problem was the unit was slow due to computer speed limitations.
In my latest setup, I am using 500 line encoders and with a new power supply, am getting 120 IPM rapids on my mill/drill (X and Y axis only). With properly tuned drivers, the following error is not a problem. Matter of fact, I like the idea of a tight system.

Would I use Geckos again. You bet your sweet bipie :})

I would not go any higher than 500 with the G320. I use 250 count encoders and can get close to 200 IPM on my mill/drill.

Ok, I just wanted to make sure before I go ahead with geckos. The servos on the router will have belt reductions that should put me around 200IPM (atleasted designed to run at 200ipm) wether i get it to go that fast remains to be seen.
Thanks for the info guys

Newbie question, what's the diff between the 320's and the 340's? It seems it may only be the ppl or pll, I don't know what this means and I need some help in choosing the right controller.

Thx

Kburn, you can read all about the 320s and 340s at the Gecko website. There is plenty of info there. www.geckodrive.com

I have 500 CPr encoders on both my Tree Mill Journeyman 300 and my enco 8X36 knee mill. I have not probklems with rapids of 120 IPM +

Hi everyone,
500cpr encoder, is it 500 x 4 = 2000??, or 125cpr x 4 = 500??
Im a bit confusing about this issue, Gecko can go up to 500 and no more than that, does it mean it accepts no more than 500 lines encoder(2000 quadrature)??
