I'm new to motion controllers, and I'd like to ask the newbie question of which motion controller I should get. They all seem about the same to me.
Maybe the better question to ask is what's the difference between controllers, esp. given their price range. Requirements: 4+ axis, less than 1ms servo loop, extra inputs/outputs, nice to have windows driver. I've read the list archives, and have seen similar questions asked, but I haven't seen the question answered to my satisfaction. If you'd like, you can respond by emailing me directly. Here's my impressions on a few of them given my lack of knowledge of the subject: ==Servo-To-Go== Good: I know someone who's had good experiences with it, 8axis, seems well-documented, windows driver Bad: ISA bus, all the software seems to be kinda outdated, expensive ==Mesa== Good: Seems like a lot of people on the list use it. Nice that they sell an H-bridge amp that plugs in. Cheap! Bad: I don't really care about the FPGA. I want a motion controller, not an anything I/O card. Is FPGA slower? ==Vital MotencLite== Good: Seems well documented, professional, windows driver. At this point in my mind, this seems like the best. Bad: Someone on the list a while back said he had some trouble with it. ==Pico== Good: Cheap. Sells amps too. Bad: Parallel port seems kinda iffy. If I understand right, I can use EMC as a controller-independent interface to do PID control. Is this correct? My application is haptic devices (touch/force feedback) for user interfaces. Also maybe CNCs, which I'd love to build in the future. Thanks, Gerry ------------------------------------------------------------------------- Take Surveys. Earn Cash.
