I would think that Spindle ON would get you where you need to be.

Which relay? One or both?
Like a 60 cycle hum?
Is power supply strong, clean enough?
In show Hal configuration
under pins
is motion.spindle-on connected to par port pin 14?
On the bright side you are almost there...

So in the MDI window you do
S1 M3
relay buzzes
M5
buzzing stops
?
or in the Show Hal Configuration you can an unlink pin with unlinkp then set pin with setp to control the paraport pins directly.
www.linuxcnc.org/docview/html/hal_basic_hal.html#r1_1_6
Also, is your parallel port 5v or 3.3v?

just relay #2
yes, I guess about a 60 cycle hum
power supply is a 5v wall wart, it powers both relays
I think the 5v supply is fine (rated 5v 700ma, but measures 5.6v actual)
this is hal config...
Owner 6 Type bit Dir OUT Value FALSE Name motion.spindle-on ==> spindle-on

If you exchange the output pins to the two relays does the problem follow the parallel port pins to the other relay or does the same relay buzz when on the other signal?
If a power supply problem would expect both relays to be a problem, if so a cap on the power supply may help.
You may also want to look at the parallel port tester...

The buzzing might be from the wall-wart, they are often not the most stable or well regulated supplies.
Do you have any other power supplies you could test with? (Black and Red on a spare hard drive power plug in the PC, for example)

Rick,
Good idea.
I will try switching pins and see what happens.
thanks

Andy,
Thanks for the idea, it did not occur to me to get clean 5v that way.
A spare USB cable would get me good 5v also, right?
I will give it a try.

Not sure how much power you need for the relays but the usb is limited.
But of course find the location of the problem with testing.
