Lost communication with Toolboard
I am bringing up a v-chonk with standard parts including skrat 1.0, and EBB42 V1.2 . All the components appear to be working: I can home, extrude, generate a height map and run the other calibration macros. But when I try to print anything the pi loses communication with the toolboard just after the prime_blob is started and the z axis starts to rise. It is very repeatable; not at all random.
So far I have:
-changed the Pi from a 3 B+ to a 4
-changed the USB cable to a higher quality
-Confirmed the usb ends are securely attached
-Tried to secure the usb c end with and without cable ties
-confirmed the 24V to the EBB42 is stable
-tried moving the cable away from the stepper motors
-read about every post I can find on the similar issues
-made changes in the /boot/config.txt to delay usb drops
-moved usb connections around on the Pi to confirm there is not a usb port issue.
-confirmed from the lsusb logs that the toolhead disconnects and then immediately reconnects.
I am out of ideas on what to do next. I would be grateful for any suggestions..... thanx.

As an update: I confirmed I can run PRIME_BLOB from the console perfectly... no errors and no disconnects.
The klippy log indicates the toolhead sends an "EOF" before disconnecting.
The dmesg log shows the toolboard disconnecting then immediately reconnecting.
Unfortunately, I can not find any information that says why the toolboard disconnects.
I also confirmed that anything sliced by orcaslicer has the same issue. Issue is resolved. The pinda sensor is connected to the toolboard with relatively large Du Pont connectors. When the toolhead passes the right rear corner the right rear motor mount bends the sensor connector as it passes. I discovered it also caused two header pins (behind the connector) to short when the sensor connector contacts the motor mount. When the header pins were bent out of the way the printer acted normally.
