Yes, the SS is original but quite old, and yes the pulley selected and ratio is 4.
I am using port 11 on the BOB witch should be ok?

Please see my earlier post of March 17.

Is there somewhere I can get information and help to solve my problem?

Thanks TPS your reply, but it bid not help, no indications of RPM on the screen. The green index light on the Mach3 screen is active and also a red LED light on the BOB indicating that the input signal is active.

Can some tell me why the rev. counter in Mach3 doesn't register the RPM even as the signal is showing up in the hardware page? (Index botten get activated - on and off).
The optho switch is working nice thanks to MN300 and is giving .6 volt and 4.7 volt when reflected and non reflected.

Getting closer (I think).
Cleaned the device and now it seems to work. Wired it up to the the mill for a test(not installed). The green light on the hardware page responds with on and off. The same does the red status LED on the BOB (G11G Multifunction CNC board Rev. 9 from CNC4pc).- but Mach3 vil not show the REW, the display just flicks wildly even if no a speed is called for.
For ref. my setup is:  Windows 10, Mach3, Smooth Stepper ver. 1.2,  BOB as above and the mill is a SIEG KX3 CNC Mill

No it do not work any more. It did work this morning, but not now.
The emitter is working and the voltage at pin 3 was 1.3v and the supply round .8v.
BTW. in the drawing  the R1 is shown as 100 ohm, but 150 ohm is actually used.

Yes, the emitter do work, checked with my camara.
I measured the voltage as you mentioned to flicker between .4 and .9 v. I tried to shelter the sensor with little effect, not notesible.
To bee sure I measured the right place I attach a drawing showing where I did the measure.
Sorry, sent you a wrong dravig. Here is the right one

I have checked the voltage of the external supply to be 5.12v (not 5v).
The device is not mounted on the mill, but is wired up to the mills supply.
I get the following readings across earth and signal: flickers between 1.4 and 1.9v. There is no differences if reflectit or not.

Is changing the power supply the only change you made? yes

Hi.
I need some more help.
When I test the sensor with a Travel Adapter giving 5.0v and 1.0amp it works fine, but when wired up to the mill it will not work at all. I measured the built in power supply at the mill to 4.88v. I think that is the reason. Can anything be done?  Reducing the 150 ohm resistor to 100 ohm?
Or is the only solution to use a separate external supply?
