Hi Guys,

I would like to run an external program automatically upon loading a file. Are there any hooks for doing with this LinuxCNC / Gmoccapy?

My goal is to compare the tools in the CAM generated file to my current tool table and make sure there are no mis-matches.

Thanks

Legend thank you!

I stop poking around for now so and just see what mesaflash reports

With a single input, it must connect to the 'A' pin.
(and the encoder counter set to counter mode)

It would require different firmware to put standard
encoders on TB3 (7i96s_p1encd has 1 encoder on TB2 and
6 more on P1)

Your mesaflash command may have failed because either you have LinuxCNC running
or LinuxCNC did not exit cleanly. LinuxCNC blocks access to the Ethernet port it uses
when running.

The .pin file just a human readable file that  describes the firmware contents and
pin connections. Its made by running mesaflash's --readhmid command.

To make new firmware, one changes the PINXXXX.vhd file and re-compiles
the firmware source using the software toolchain for the particular FPGA.

 

Hmmm....

So with the existing firmware, it sounds like I could connect my two MPG encoders to say the first two MPG inputs on TB3, and then connect my two potentiometer based frequency sources to the 3rd & 4th encoder inputs on P1?

Assuming that sounds acceptable, if I want to get the frequency values from the P1 encoders, should I be wiring my frequency sources, to A, B, or IDX of those P1 encoder inputs? I'm not sure which of the three signals is the source for hm2_7i96s.0.encoder.04.velocity
