Thanks Richard, so there isn't any RPM display coming from the encoder directly.

Now I need a link to whatever?counts the pulses.?

I want to stick with known working devices.

That is an OLED display used to show the spindle rpm. There is a one per rev pulse from the Mega which I look at with a nano to drive the display.

Thanks Richard, that really helps to see pictures. It would really help if someone would do a video of using the RELS.

What is in that rectangle to the left of the LED?

You have it Ralph!
To help maybe see the pics of my control unit and Joystick box.
The main control unit shows the four Left, Right, Front, Rear buttons with the Select button to the left and a reset button top right. The two 25 way D connectors connect to the Joystick box and the main Power and dries box.
On the Joystick box you can see the four "Limit" buttons. The "Ring" around the centre of the button illuminates. The Red button enables Rapid travel. These boxes have been around for a while that is why they are a little roughed up!

Just read the whole thing again probable the 4 or 5th time and it "might" be sinking in.

The "limit" switches are virtual not actual limit switches.

It actually makes sense. They are set for distance travel limits not to prevent overtravel of the leadscrew.

Ok moving on!
