For the money, you can't beat the Gecko. I have been using geckos for milling, lathe,and cutting vinyl machine. Sometime, gecko are pushed to work 5x24 hours. I have no complain so far. I will continue to use it for my next project.

Stepper motor drives are much more complex. Steppers are pulsed at 10 -20 times their rated voltage. Then the voltage is chopped to rated voltage at idle/hold. Seems like a recipe for problems. I use the Gecko 320 servo drives and they are one tough little beast. Just the other day I was drilling holes all day with the Gecko whipping the knee of my Bridgeport up and down peck drilling and the servo warmed up but the Gecko stayed nice and cool on the heatsink under the fan. When I was doing my retrofit, I layed a Gecko320 down next to one of my Nema 42 servos and was not convinced it was going to work. It's tiny in comparison. My motors were 4.2" diameter X 17" long body, a bit shorter since I removed the brake. There are pics of my machine on the CNC-pics group at yahoo. Yes, Gecko 320's control those servos with rapids on X an Y of 120 ipm and 60 ipm on Z. Much to my amazement. > I'm sold on them and wouldnt even consider using any other drive. 15 months of continual use and not one problem. I was concerned at first about getting into the middle of a job and not being able to complete it because of a possible drive failure. I've become very complacent about their reliability. I even designed the enclosure so the drives on their heatsink easily slide out of a slot in like a tree in front of the fan because I thought I would be changing them occasionally.
