I answered my own question by reading the docs!
setp parport.0.pin-01-out-invert 1
Is exactly what I needed, I went looking for -not pins with no joy and never thought to look at parameters

Added APTSource program extension and path to [FLITER] section

Thank you very much.
I have been planning to add encoder support as mpg for a long time, but it was not my priority because I do not have the appropriate equipment.
But today you gave me an opportunity, so I connected a regular encoder to 7i92 and performed tests.
In the condition as below, you can move the X axis by turning the encoder, but only after the axis has been referenced.
I haven't tested any more because I don't want to look for and solder switches right now, but judging by the code it must work.
(The setp axis.x.jog-enable 1 line is for testing only and should be removed afterwards.)

It´s a me again.

So far I got the Gildemeister NEF 500 Plus Lathe running again, with the keyboard i was even able to make some chips. Homing now works since the updated version of Pncconfig wizard seems to have a few bugs left for the 7i97T. On bug for example is, inputs that are "inmux.00" are named "in.00" in the .ini or .hal, not sure right now but that occured every single time i changed something with the wizard.

But let´s get back to the problem I´m facing now. Trust me, searched two whole days to find a solution bymyselfe.
Here´s the physical setup where i´m coming from:

i have two Handwheels on my machine, they have A /A b /B signals, and are wired to encoder 03 and encoder 04. In Halshow i can see the hm2_7i797.0.encoder.03.count corresponding to each wheel. That worked right away.
The wheels should be always enabled, except when running a command or a programm. The wheels are fixed to their axis. 03 is for Z axis and 04 is for X Axis.

I copied and wrote tons of .hal lines but nothing seems to get the axis moving when i´m turning the wheels. I tried to set all enables that are somehow related to axis jogging to true in Halshow. nothing worked. In the documentation the link is broken to that one site for hooking a jogwheel. And every code i copied was obsolote, since the names of the pins and this has changed. I end up with "pin doesn´t exsist" all the time. You don´t have to tell me the whole solution, but i´d like to understand the mechanics behind Jogwheels and Axis jogging, how do i link the jogwheel count to the axis count so it moves ?
 

Hi
I have seen recent topic of @tommylight about filter for pts files. This help me to start writing the postprocessor for apt files.

I can manage simple words and convert to gcode.
Next to steps :
1- process circular interpolations
2- make it working in LinuxCNC as program filter, actually only works stand alone.

I am sure that’s python code is not as beautiful as it should be but that’s working.

Hmm, this might work
parport.<p>.pin-<n>-out-invert 

 
I decided to build a parallel port LinuxCNC config cos I'd never done one before. All went very easily after firing up stepconf which got motors moving straight out of the box.

But now I got problems with the PWM to control the spindle because the volts were running the wrong way eg 24000 rpm = 0 volts and 0 rpm = 10 volts. I thought it would be easy to invert the signal but to  no avail.

I tried to adjust with a sum2 component so -24000 + Commanded RPM = - desired RPM. This turned out to be a dry gully too.
I figured if I had to  convert it to an absolute number I could do that but halshow promptly showed me that -24000 + 12000 = 0
I got rid of the negative and used a gain of -1 and I still got the same wrong answer...

So what is the trick to invert the PWM value?

Most people on this forum in your position have ditched CommandCNC and moved to QTplasmac with a Mesa THCAD to measure torch voltage and let Linuxcnc manage the THC function internally.

Time to dust off this thread with a small update.

I finally had some free time, so I decided to make some progress on the electrical cabinet. We created a dedicated section for the two braking resistors (2 × 1.5 kW) and the transformer for the axis servo motors. We also installed a steel mounting panel where all of the electrical components will be neatly arranged and secured.










And here's the donor machine that I'll be salvaging some of the smaller parts from. ?




This is probably a good time to mention that if anyone is looking for Fanuc servo motors or drives, feel free to get in touch. ?

 

my servo motor starts to hover on zero position, it runs smoothly on the given rpm, but when it comes to halt and wanted to stop on zero position, it starts jerking and sometimes it gives er100 error or it just hovers on zeero position. my motor model is ELM2H-1800LD130E-HD. and drives is EL7-RS2000. my arm is connected radially.

I believe you might want to contact CandCNC tech support.
