Spindle indexer help please

[Len-Tikular]

Thanks Adrian,

I have amended my sketch and I think it is now correct,
Blu = In1
Red = In2
Green = Gnd
Yellow = Vcc What would you recommend the supply voltage ?? Specification attached.
How do I configure MAch3 turn to read both these signals ?


However
Just in case we cant get this working I have fitted a single inductive pickup which gives a spindle out as follows.

M3 S1000 = Indicated True Speed = 60
M3 S5000 = Indicated True Speed = 360
M3 S10,000 = Indicated True Speed = 740
M3 S15,000 = Indicated True Speed = 1120
M3 S20,000 = Indicated True Speed = 1500
M3 S25,000 = Indicated True Speed = 1888

It looks fairly linear. But how do I get the requested M3 speed to be equal to the Indicated true speed ?
The output from my BOB is a 0-5Vdc
I have set pulley No1 to min speed to 0 and Max speed to 25,000
Spindle feedback and Spindle averaging are both checked.

That diagram is still wrong. The LEDs should be powered continuously. It is the transistors which are generating the signals on the blue and red leads.

When the solid part of the disc is between the LED and the transistor, there is no light reaching the transistor, so it does not conduct. This allows the red/blue wires will be pulled high by the BOB.
When the gap in the disc comes round, the light from the LED passes through it, hits the transistor and it switches on. This pulls the red/blue wire to ground, generating the pulse needed.

The Boxford circuit diagram appears to show the sensors powered by 10V, so the sensors should have resistors for that supply already.

Sorry, I've never used Mach3 so cannot say.

Many thanks, sorry for being a pain, I didn't realise you were not a Mach3 user.
I did have the Boxford Schematics but somehow lost them in the course of time.
Can you remind me of a link where I can get them.

Good news is I now have the spindle true speed and requested speed allllllmost the same and
Using a macro M6start I am now able to run my toolchanger, it needs tweeking and the addition of a homing sensor on the turret would be a big help.

Thanks
