  Interesting. I suspect the trigger angle when used with DRO #66 wont properly do mutistart threads, Im working on a fix for the angualr sensing, it used to be base don # of interrupts as well.

Ill have some new code for Brian soon I think..

ART,
I just tried the latest version .032.
I  get no RPM or  INDEX at all. So threading is realy broke in 3.042.032.

Unfortunately for some stupid reason my postings bounce / never get posted in the Yahoo group.

Thx, Ill try it here in the morning. I downloaded the .32 posted and it runs here, so I just need to figure out whatever small error seems to be in there on some xml's..

Can you verify.. you dont get an index led lit on the diags page even if the chuck is hand rotated to the index input?

 Im getting confused by the lack of Index.. I cant replicate it..

ART,
- In diagnostics, it shows the index is working ( lights as you turn the spindle ).
- In the Turn Diagnostics ,will show real time rpm, but there is no indication of "spindle rotation sensed".
- There is no rpm dispalyed in the main Turn screen DRO.

  OK, this morning I deleted my driver, downloaded .32 version , and copied in my xml.

I did an M3 ( you have to in this version, spindle must be on to read RPM ), and turned on the lathe spindle.
I get RPM no problem.

  SO Im thinking it must be something xml related or that plugin. Did you delete any threading plugins for
your test, they may stop it from working in the release version.

Maybe I should try your xml.. though it usually has to be changed so much to match my system it isnt a great test.

 So can you delte that threading diagnostic? And see if you have spindle relays turned on so the system knows the
spindle is running when you do the M3 to turn on RPM sensing.

Thx,

ART,
BTW, This is for ver .032 ( same goes for i posted in reply 674 )
Tried using "working off line".
- in MDI line - G95
                 -G32 Z-1.0 F.050 Z axis moves but you will get the error "No SPINDLE FEEDBACK SEEN....."

Reading your reply i and now using the attached XML, tried the M#, no joy.
I am not using a VFD or any motor control.

Hi Rich:

  Use ports&Pins and goto the Spindle options tab, uncheck "Disable Relays" and then apply it. I suspect youll find you now can read an RPM when an M3 is in effect.

OK,
 I had the the Relay Control and Disable Spindle Relays checked.
Didn't need any of that stuff with no VFD or motor control!

SO......
- On unchecking Relay Control /Disable Spindle Relays ( and M3 is left at ouput #1)
  Also have motor control unchecked
- Spindle Enabled ( config >ports & Pins>spindle enabled / green check, but no pins out or ports defined )    -  in config> ports&pins >no outputs defined.

Then I will get spindle rpm readout in DRO.
In diagnostics red flashing light for output 1, and Spindle On box yellow.

Now can run a threading gcode  from the wizard.

After running the g code, the ouput 1 no longer flashes.
Enabled the Turn Diagnostics 1.00.1

How is someone to know what they need to change in their configuration to run Ver .032 if they just have
no motor controls?

Rich:

  You shouldnt need to. Ill change that for the future versions. I found that when the spindle stopped, the RPM locked due to the way the measurment system works. SO I made it zero the DRO if the spindle was off. Unfotunatley theres a long time bug in that SpindleOn/Off sensing requires there be a spindle on signal somewhere in the setup. Ill fix that so that its properly modally sensed, and find a better way to determine that the spindle has stopped.
