Hokoed up a PC to the mill
Sorry for a lousy picture.

You'll have a lot more fun once you have the servo loop closed and can play around with precise positioning, accel/decel, homing, etc. Remember to wire the index signal from your encoders back to the control for eventual use for precise homing. |

I will definitely use the index signal. As of now, I do not even know, yet, if my encoders work at all. Another big chunk of work is wiring all external things like limit switches, buttons etc. i |

My mill does approximately 70 IPM right now, I think that it is slow enough for homing, no? i |

My mill does approximately 70 IPM right now, I think that it is slow enough for homing, no? i Most likely not, but it depends on how fast your decel rate ends up set at. You will probably want to home at around 10 IPM so you can drop down to 1 IPM when you detect the limit switch and creep up on the index without overshooting it. You'll figure it out once you start testing your homing. You can also either adjust your limit switch position slightly, or your encoder position on the motor shaft so that the index pulse isn't too close behind the limit switch trip point. The key thing with decel switches is that they allow you to home at rapid speed most of the way through the homing process, which on a machine with long travels and high rapid speeds can make a significant difference in homing time. |
