I guess you're right. Thanks.

It is attached to a lathe spindle, for threading with Mach4

You either have encoder+index or index only.

Using the encoder, PoKeys will track both the speed and position of the spindle, compensating for position errors due to spindle speed variations. Index is still required.

Without encoder, one index per rotation can also be employed for threading. Multiple pulses per rotation are not supported. If you have a gear tooth, it is simple to convert it to an encoder - just position two sensors offset for less than half of the tooth width and feed the signals from the sensors back to PoKeys as encoder signals.

When I use an encoder which has 3 channels (A, B and Z) do I still need an index sensor?

Do you have any progress with the M16?

Hi Craig,

I already did. I also created a new lathe profile. I have uploaded the profile folder if you (or anyone else wants to help) want to take a look.

Is this an answer for me or for @joeaverage?

And some screenshots of the setup. Please let me know if more info needed.







I have played with the index debounce but didn't change anything. I used to use 20 in Mach3.

Guys, I get the spindle working. I mean, M3 and M5 is working. I also get the green light when the index sensor is aligned with the slot on the disc. However, I don't have any index reading. When I hit the CW button in Mach4 the spindle starts rotating but the real spindle speed always zero.



- The index sensor is connected to PIN 15. I did the Darwin setup. Also mapped index to index in Mach inputs screen.
- I set the base PWM frequency in Darwin diagnostics screen to 300.


I wonder why there is no complete documentation for the Darwin plugin.

Hi Craig,

The machine I am trying to setup is a lathe. I need spindle indexing for threading. I have to get it done.

Best,
Suat
