Replied by RMJ fabrication on topic Ethernet connection to Mesa 7i76e disconnecting on its own after one minute
I turned everything off except the PC and it no longer disconnects on its own and it doesnt show my mesa connection. But when I turn the mesa board and the machine on it starts disconnecting again every 45 seconds. So now I think you guys have a good point and maybe this could be hardware related.

Wire EDM 4 axis, seems to be open source and 3D printed was created by tommylight
Not my stuff!
Bumped into this, looks nice and usable

Maybe 5 axis with rtcp. My plan is to make one with 5 axes this year that would work on rpi5 + 7i96s + touch screen...otherwise I won't change it, although I've already forgotten how to insert the procedure exactly (which file where), but it looks perfect. Thank you.

I use the same and it works well.

Here is the list of supported drivers from IgH:  IgH EtherCAT Master: Device Drivers

Any chip which uses drivers on the list is supported.  I226 uses igc driver.

I think I will go ethercat and sell the mesa. 
I completly ignored the fact my vfd works with rs485, thanks for the reminder to check.
Leaves only the decision on drive i/o vs central i/o. I found some deals on the beckhoff parts
ek1100, el1809, el2809 
are those the right ones?
I will be using 8 24v end sensors pnp nc.
Many thanks again.

I thought it would make sense because the Mesa card was already purchased and paid for. ... it seemed not final what was missing.
Admittedly two network adapters probably complicates things.
When you just want to eat pickles and cake without getting "the look", being half pregnant does the trick.

Replied by grandixximo on topic Probe tripped during non-probe move deadlock
"Queue is not empty after probing" error message, is the issue I am hunting for, trying to find anyone that can reproduce this, and see if my patch fixes it, I think your problem is something different, and it is correct that the machine stops when the probe is flickering, the "Queue is not empty after probing" is something different that in theory should not happen, trying to find users that get this message.

I don't see anything obvious wrong in the hal/ini files

I would try using and external 5V supply  as a way to debug the issue
but its a pretty mysterious problem.

Success.

My suspicions were correct - there are undocumented parameters to set in the drive before the digital outputs can be activated.

Stepperonline advised the following:
Warning: Spoiler!


Parameters C04.59 and C04.5A are not in the manual.  They are, however, visible in the tuning software (see attached screenshot).

I've attached a bare-bones xml file which will create HAL pins for all five digital inputs, and two of the three digital outputs.  The last output - DO3 - is reserved for the motor brake and commented out.

As usual, thanks to everyone for helping out.

You can use RS485 Modbus to control your VFD so its not really a problem until you come to the encoder if its needed. Threadmills are a lot easier than rigid tapping.

Also, as of now everything is new on the PC. I have an older dell optiplex I can play with if we think thats the issue…

here are my hal and ini files. I only have a few buttons working at the moment so it should be pretty generic so far

OK that sounds more like a hal issue or maybe hardware (Memory?) issues on the PC

Can you post your hal/ini files?

  When I say crash, I mean the computer shuts down and reboots.

The 7i77 is powered by an external 5vdc supply. Here are some pictures of the wiring 


I am getting 5vdc between the screw labeled vcc and 0vdc. Interestingly, I can start LinuxCNC with the encoder hooked up and it will not crash unless I move the hand wheel. I used halshow to verify other buttons are working (joystick, start, stop, etc.)

power supply for 7i77 is 15w/2.4 amp
