Jeff, regarding the rotary encoder homing on a linear axis... We use a similar system, but use an additional prox switch that says, 'the home is inside THIS revolution'. I use it on a device where the encoder is on a worm gear that turns 90x for every 360" of a C axis. But the idea should apply to a rotary encoder on a linear axis. Some hal-foo is needed for the 'close to home' prox switch. Oh, beware being too close to the prox's edge ;) Try to have 'home' at least 1/2 turn past 'close to home'. regards TomP |
