One last note.. Driver encoder #3 is really Mach3 encoder #4, in the driver the numbering starts at zero.
Ill add one to that in future..

Hi, Art

The data scope isn't scaling the ms vertical to match the min/max stats value, I'll try the 1.03 plug in in a few minutes.

One further note for Vista users, when you use the control panel to uninstall the driver, you are asked "Do you wish to delte the driver software?" Select YES
otherwise DriverTest will not install the new driver.

Thx

(I just fought Vista for an hour to get mine to load.. friggin Vista.. Sucks hard..)

Hi, Art

Thanks for the Info.

Now have Both Computers showing Scope Info.!!!  :D

The one with High "Last Index Rotation us" problem was being caused by having Mach3's Kernel Speed was set to "100K".  >:D

Scope trace seems to only work up to 512 samples hear.

Have Fun on your Vacation, Chip  ;D

ART,
Installed the version from reply #277, did all - checked all - still is not working properly on my end. 
Have a nice vacation.

Nice readings Chip.. just like mine. Ill check into why the 512 limit when I get back, and Ill help Rich get loaded .. must be something wrong there..

I see your divider is now correct. .excellent..

Thx
Art

(See ya's in a week.. )

Hi, Rich

I think I've found the problem your having, You need to have both index & timing enabled with an active pulse stream or you'll get the high rpm indication.

The data scope doesn't have much pulse height if the Number of Slots is 1 ether.

Chip,
HMM.....so you actualy need another " active pulse stream "  and not emulating one of them as i did before or you'll get bum data as noted by ART's reply below.

------------------------------------
  ONLY IF YOU ARE USING INDEX AS A TEST INSTEAD OF SLOTS.
        but the index is checked for emulated ( if you don't enable the index you may not get a graph, may be a fluke?? )
   NOPE< MAKE SURE INDEX IS NOT EMULATED>
- in config>ports and pins>input signals - enable the index and timing using the same ports and pin numbers
---------------------------------------------------

Thinking now, and that is dangerous!  ;) 

Just leave the timing disc as connected since it's on the back side of the spindle (i made an adaptor to easily make
additional slotted disc's from CD's - use the boy's rap music CD's   >:D  ) and put the index in the chuck / mount  a pickup on the crosslide / 5 volts and two temporary wires for inputs using the 2nd PP .....easy......

I figured i would start off with four timing slots and then do one with say 20  to 30. Disc diameter is limited to
about 3.25".

Hi, Rich

If both are from the same, Examp. 10 you get this.

Give me a call.

The index will only have 1 slot and the timing will have 4 and they wil be inputs from different pins?
Do the inputs need to come form the same PP??
