Help needed to get my 7i76E + 7i85S + 7i73 on my mill going.

Have today 3D printed some parts for the gearbox discussed earlier.


Will be glued to housing


SMC D-Y7P


Arm to be glued on selector.

Will try to get the inductive sensor for Hi/Lo gear fixed hopefully tomorrow.

Looks nice!

Gday Rod, thanks.

I hope it will serve me well.

So now also Hi / Lo gear detector in place. Using Contrinex LHK-3031-303 with adjustable 'focus'.


Time to install the cables to a RJ45 connector

Cabling ready and tested so now it is time to tinker how to get this all working.



With above I get 100 to 2500 rpm, spindle motor fixed to high speed = 2850 rpm and Hi / Lo + Gears A to E.

So what would be the best way to get this working? Yes there are combinations of settings allowing two ranges.
Any pointers on what to read?

Have a look at lut5 as that gives you 5 bits of input. Its pretty cryptic but I am sure Andy will help you. He's the expert on it.
I think once you resolve lut 5 to a speed, you should be able to use a mux2 to multiply the result by 1 or 2 depending on the hi/lo gear selection.
