How do I make spindle-enable work correctly ? was created by Jake
I have been getting closer on the Hurco. I can not get the spindle to run, I have to make the SSR 3 true to enable the spindle drive. When I hit the spindle foward/reverse in the UI it will not make it true. I have tried to go into the MDI and M05 to stop, and M03/M04 Sxxxx with no luck. I think I need to add some other links to tell it when M03/M04 is called for SSR03 should be called for.
Any suggestions?
Thanks!

Not knowing your machine, I can only guess.
If you use halmeter to look at the Spindle-enable signal, does it behave as expected?

Analog spindle drive, with Pico PPMC hardware.
Jon said the spindle won't start with a zero speed value. I have to have a contact close to enable the spindle drive. Watching the spindle enable signal and the PPMC out 03 they stay false. Even if I MDI M03 s100 or something similar. I don't have a forward or reverse command, it's all handled via the analog input 0-10v for speed and direction. Which is handled by the PPMC DAC card. I was going to add the spindle forward and reverse in there so if spindle forward, reverse, or on is true it will make the output true.
I never made it out there to try it this afternoon.
Thanks again!

I tried swapping from spindle-on, to spindle-foward and still nothing. I am not able to get my 03 SSR to come alive to allow the spindle drive to run. I do not get any error messages when you attempt to run it either.
Any other ideas?
With the Pico gear I have the DAC card to give the spindle drive velocity and direction there. I just have to close a contact to enable the servo drive.
Thanks!
Oh yeah my MDI commands are able to change the states of the GUI pins so that portion is actually working.

What do you see if you watch the Spindle-enable signal with Halmeter?

It stays false no matter what I do
I just came to the realization that there is no tool loaded shown in the GUI. Could this not allow a spindle move at all? (There is a tool in the machine) I cant see where the tool table is loaded and can not load it. I had tried with spindle-on and spindle-foward and watched them in the hal meters. they never come true

That's curious.
In the MDI window, if you issue:
M3 S10
Then you should see motion.spindle-on go true and your Spindle-enable signal should follow it.

curious is not exactly the word I have for it at the moment.....
Yeah I just tried it again
M3 S10, my GUI button pops down, I have tried with spindle-foward, and spindle-on both will not come true. I am at the machine now. I have tried all three, I do have the first two # out right now. The last one I copied right from linuxcnc.org/docs/html/examples/spindle.html#_spindle_direction
Or is there somewhere else that needs to link the two actions? I would think if it was something like the "no tool" condition I would get an error message. I am pretty lost right now.

Does anything happen to the other motion.spindle... pins? Can you see 10rpm for example?
You don't need a tool loaded to operate the spindle. I don't think you even need to be homed.

I can not get the RPM's going, rope pull cord on the spindle does not register significant movement. spindle-revs changes, but stays a very small value. Looks like I need to double check the spindle encoder connection. I thought that one might be a challenge as its powered from the spindle drive not the encoder card like the rest of them are. But I wonder if its not working as I do not have a spindle on available.
