net joint-2-enable => hm2_7i78.0.stepgen.02.enable
should be
net joint-2-enable => hm2_7i97.0.stepgen.02.enable

So there is currently no built in way to do this.
The probe routines in master are burried in probe_subprobe.py
github.com/LinuxCNC/linuxcnc/blob/master...ets/probe_subprog.py

The is a pre and post function in there.

prechecks()
postreset()

You could hand edit them to add your calls.
I guess adding an INI pre and post command might be helpful.
What does your calls do?

2.9.4 but can apply patch to 2.9.4 source.

Thanks for the quick reply, problem resolved! Now I seem to be running into troubles configuring the stepgen on the 7i78. Do I need to call that board out separately or include stepgens in the board config for the 7i97T?

Here is what I have in the main.hal
loadrt [HM2](DRIVER) board_ip=[HM2](ADDRESS) config="sserial_port_0=00000000 num_encoders=6 num_pwmgens=6 num_stepgens=0"

It is failing here:  net joint-2-enable => hm2_7i78.0.stepgen.02.enable
main.hal:255 Pin hm2_7i78.0.stepgen.02.enable does not exist

Alright. So I have finally figured out what you were pointing to Todd in your links and have activated the .py script and included the M101 and M102 as MACROS into the ini file.

I did this by shifting the default templates out as it appears there can only be a single version of User Sidebar at any one time.

I noticed that the .py script does not seem to show activation of the button on click/toggle. I tried un-commenting the Style sheet, but this is a little above my pay grade.

So next steps is setting the First Macro as toggled on, and when setting the next button, setting focus on the button pushed. Can anyone help me with the .py scripting that would update the button selected in the MDI button .py script in the following link: github.com/kcjengr/probe_basic/pull/84

Thanks in advance.
I am nearly there with an operating system.

Are you setup to build LinuxCNC from source?

I have a patch from a LinuxCNC developer that may fix this issue.

 

No special firmware is needed for THCAD (if you have a free encoder)

I'm having the same issue, but with a 7i97T + 7i78.  PWM Version is reporting 0 when doing the HMID Read.   

Could you please provide the updated firmware for this combination as well?  Additionally, I'll be using a THCAD with QTPlasmaC.  Is there any custom firmware needed?  Not planning to use an additional THCAD for Ohmic sensing currently.
