"pwm/dir" (Out1) switches for spindle CCW was created by juergen-home

Hi there
A question about my configuration:
1. I have a HF milling spindle which needs only to turns clockwise. The PWM canal (Out0) works fine. My config for "pwm/dir" (Out1) is set to a relay output (P17/"GPIO7"). The relay should be on when CW is commanded but here it is on when CCW is commanded. How config it so that the relay switch on when CW is commanded?

I've never used a parallel port. Do they have -not pins that are inverted for each pin? If not, there is a not component that inverts a pin.

... it is driven by a 6i25.
I have tried to invert, but that does not the trick for me. It inverts only the Relay signal for CCW but I need the action on CW.

Something like this? (no sure if you need inversion or not)

# Invert the DIR signal
setp hm2_6i25.0.gpio.007.is_output true
setp hm2_6i25.0.gpio.007.invert_output true

net spindle-ccw hm2_6i25.0.gpio.007.out

Thanks Peter for coming by. I put your 3 lines in my .hal file but there is an error message:
...
Debug file information:
Note: Using POSIX realtime
./ttm_a.hal:298: parameter or pin 'hm2_6i25.0.gpio.007.is_output' not found
2077
Stopping realtime threads
...
Perhaps this is because gpio.007 is "hm2/hm2_6i25.0: IO Pin 007 (P3-17): PWMGen #0, pin Out1 (Dir or Down) (Output)"

Seems this gpio.007 is bound to "pwm/dir" (Out1) for signaling CCW, what I want to do is to use it as a signal to enable my VFD while CW rotation.
Because I'm low on outputs I want to use this gpio.007 with the relay.

What fIrmware are you using?

5i25_5ABOBx2.bit should have the correct pinout and GPIO 7 is just GPIO on that firmware

What do you mean with firmware? The bit-file?

If you mean my IO Connections for the 6i25 they are shown in my first post in the last source code section.
I made my own bit file matching the in and outputs of the mach3 bob.
The 5i25_5ABOBx2.bit is matching my china bob?

Can I remove the "17 7 IOPort PWM 0 Dir (Out)" in the bit file and make a nomal I/O Port out of it or must these PWMs come in pairs of PWM and PWM/DIR?.
If not, can I change a component so that the relay clicks with CW and not with CCW?

Yes, it has a slightly different pinout but is designed for that BOB.
It supports all 5 Axis (on each BOB) so has a stepgen pin on IO7=DB25 pin 17
but was designed to easily reclaim the pins as GPIO since it uses stepgen
8,9 for the per BOB 5th axis so by setting num_stepgens to 8, you can get 4 stepgens
per connector and still have the relay GPIO free.

You could also just recompile your bit file and change the PWM dir pin to just a GPIO pin

The problem with using the PWM DIR pin is that it depends on the PWM sign, this
may work if you connect the PWM value to the signed spindle speed command
rather than the absolute spindle speed command (you may still need to invert the DIR pin).
The advantage is that this may work with your existing bitfile.

At the end it was easier for me to compile a new bit file without the pwm/dir (I/O 07 PIN 17) and use it as a GPIO. It is working now.
Many thanks to you Peter!

Another question is about my "26 HDR" internal port of the 6i25 , I wanted to do my own encoder pcb but now I found a used 7I52S.
How to modify my vhd-file to do so and how should the cable from 26 HDR 6i25 to the 50 HDR 7I52S look like?
I don't now if I can use all functionality of the 7I52S but at least the 6 encoders and the rest filled with (stepper)outputs?
Should I open a new thread for this?
