Taig Lathe conversion to LinuxCNC: M3 is not turning on spindle

I am moving away from Mach3 (yay!) and created a StepConfig from the Mach3 XML file. I had to tweak some settings, but in the end the X and Z axis are moving properly. On the pin configuration I had to add the ESTOP OUT pin, which is working now. However, M3 is not turning on the spindle. With a scope and while using Mach3 I figured out that the spindle turns on when pin 16 goes HIGH. The spindle doesn't use PWM, it's just single speed. So, in the parallel port pin setup I tried Spindle ON, Spindle CW and Spindle CCW for  pin 16, but nothing happens when I issue M3 on the MDI or when I run a simple GCode program. On the scope, I don't  see the pin change logic level when I issue an M3 command. I also tried to set Mist Coolant on the pin but M7 doesn't do anything either.

The parallel port is set in OUT mode. As far as I understand, that makes pin 16 an output from the PC to the lathe. I have 3 parallel ports on the PC and I tried them all with the same result, thinking that maybe pin 16 was unresponsive on the first port.

I'm on LinuxCNC 2.9 and I am attaching my HAL file if that helps. 

Any suggestions?

Thanks

 

Your 'spindle-on' signal is not connected to anything:

Try:

As for 'M7' add this to your hal:

Thank you Aciera!! M3 is working now with the HAL line you suggested.

Is this something that could have been done from StepConfig? Or do I have to edit the hal file manually?

Thanks again for your very prompt help.

I'm not sure but I guess you did not configure a spindle in StepConf hence your hal file has no spindle entries at all.
