![]() 2929 forum posts 41 photos | Thanks Jason and Bob, gives me a starting point. How this has come about is because I am slotting large bronze screwheads and the slotting saw is not happy. So I upped the rpm and it was fine. So I felt I need some reference of the rpm of the cutter. I will follow this up and see what I can do, Thank you. |

![]() 2929 forum posts 41 photos | My X3 is cogged belt drive, not gears like Jasons. I can do nothing on top as the spindle can go downwards if I need Z drive facility. I can perhaps place a sensor under the head and have a mark on a collar under the head, I wonder if it will get in the way there? Perhaps i shall continue to fly by the seat of my pants regarding the cut. Clivve |

555 forum posts 27 photos | Clive, I do not know how similar your X3 is to my little X1 mill but I have added a tacho, see: http://mikesworkshop.weebly.com/mill-tachometer.html The tacho unit was supplied with a hall efect sensor but the sensor was too large to fit in a convenient place so a made a simple optical reflective sensor which works well using a reflective strip on the spindle.
