A master student downstairs just started to do something similar. He needs to steer a target to wherever his femtosecond laser beam h happens to be. He settled for a Joy stick with switches rather than potentiometers. Speed is going to be controlled with a 12-way switch. > Are steppers or servos better for this use? You'd have to define the metric of "good" in your case. Anyway, I would prefer steppers. They are much sloppy and much easier to control. > What should I use to control them, Arduino or a generic motor > control circuit? ATmega + dedicated power chip would be the no-fuss solution. Arduino is more sexy, though. ---<)kaiamrtin(>--- -- Kai-Martin Knaak Email: [email protected] Öffentlicher PGP-Schlüssel: http://pool.sks-keyservers.net:11371/pks/lookup?search=0x6C0B9F53 _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
