System index restored. Oil in switch. Status is now the same as my post number 706.

It's the same.

The spindle on LED comes on but the output LED for the spindle in diagnostics does not flash. After spindle has been switched on once manually, then entering S1000 and M3 as 2 separate entries works the same as entering them as one entry. Spindle LED illuminates, output LED flashes and spindle starts.

When I went to the shop to do this, I noticed that I am now not getting any speed indication at all. Reading is always zero RPM and Index LED is not registering a pulse. This was working fine a couple of hours ago. Restarted mach, rebooted computer, but at the moment I am not getting a pulse on the index.

Hi Art

Understood.

Another observation as follows:

Start mach 3, run M3S1000 from MDI or G code program, spindle LED lights but spindle motor doesn't start.

Repeat this test several times, same result.

Load 1000 into required RPM DRO and select spindle button on screen.

Spindle starts at 1000 RPM

Now run M3S1000 from MDI or G code and spindle starts correctly every time.

I have repeated this several times powering down the computer between tests. It seems that M3 will not start spindle motor unless it has previously been started manually (by the spindle button)

Hi Art

I loaded the application you attacthed into Mach 3, replacing the existing one from version .032. (Was this right?) Version in help/about shows 0.030.

It seems to solve the problem. RPM indication is showing true and application end RPM is closely following rotation speed realtime in turn diagnostics.

One observation is that in turn diagnostics, spindle feedback is showing as being disabled, whether or not "use spindle feedback in synch mode" is enabled in ports and pins.

Yes the index is indicating on the diagnostics page.

Hi Hood

Thanks for your help. No, the problem remains after carrying out the test with the spindle relays.

I don't think it is a problem of auto versus manual spindle control, as I am seeing the problem under both, although it does appear that others who are not having any problems are running the spindle under manual control.

The index signal is getting through as can be seen by a reasonably stable and true speed indication  in the rotation speed realtime box in turn diagnostics. The problem appears to be in the conditioning of this signal as displayed in the application end RPM which is negative and is the same as the spindle speed indication given in the true speed DRO. Further details in my other posting " Indexing problem with R.042.032"

The same problem existed in versions .30 and .31.

Probably best to transfer this dicussion to the "Problems Threading on the Lathe" thread

In version .032 spindle must be on before you will get a speed indication. Either click on the spindle button on your screen, or run an M3 command from either the MDI input or from a G code program.
