    Maybe you could get something like this in that small space so you wouldn't need the belt. BTW, I did not get a cost for it, was just browsing. Also, you would probably need some conversion logic interface. But it looks cool.

    My fark up.

    I thought it was a solid shaft encoder. NOT. It was a hollow shaft with two missing set screws. the solid 1/4" shaft just slid out. Should be running shortly after I get to town for parts.

    I've had the same style encoder running on a 1/4" timing belt for 10 years on my other mill.

    So it is a through hole encoder?

    Not really. it has a 1/4" bore 1/2" deep. I got it used off another piece of CNC machinery. Been in my parts box for YEARS.

    If this don't work, I'll go with that automation Direct offer, mentioned above.

    " I'll go with that automation Direct offer, mentioned above"

    I would go with the Heavy duty version of the Koyo.
    A few more $$'s but probably worth it for that application.

    OK, got the spindle all up and running with S codes to command speed. I ended installing a new encoder from Automation direct. Had a bit of trouble with the test spindle routine but got it going with Camsoft support.

    Yesterday did the bloody awful job I've been putting off, final cleanup of the coolant sump. Some real nasty sh*t has been growing in there for years. turned out to be easy once set up. I cleaned out my wet dry shop vac and set it up to suck water. Set up the hot pressure washer. Alternated between washing and vacuuming till it was clean. Did **** off SWMBO as my clothes looked like I had been swimming in a coolant sump. I looked about the same.

    Today, got the home routine debugged and soft limits set up. Just a tiny bit of work left for tool change logic.

    Did a trial of Estop when running G0. Machine losses position. Not a huge deal as this should only happen in a true emergency and the machine can be re homed. Also if axis are moved by hand under estop, machine does not see the move. I wonder if a re-wire as per the red lines to by pass E-stop would cause problems? I've left encoders powered under Estop on my other installs.
