Thanks for the details. Since I'm largely on the right track, I'll give it a go using the expansion connector pins instead of CONN_LCD. I'll have to work the overlap with the BLTouch connections in place now, but that is workable.
Thanks!

I'm' working on my third and most advanced conversion to Duet WiFi and I've hit a snag. In order to put both my Z-axis steppers on internal drivers for bed compensation, I've been trying to repurpose the onboard E1 driver, and then put that extruder (for a dual extruder system) back into the configuration using a TMC2260 BOB. I originally thought it would work like a Polulu-style board as described in Using External Stepper Motor Drivers, but that didn't pan out. After multiple searches, I found this post TMC2260 on Stepper Channels 10 and 11(asking related questions, but not exactly the same situation). I'm not interested in building my own board from a bare chip -- I was under the impression this BOB would make it possible without that kind of scratch build.
Before I spend time and take any risks, I want to get some guidance on my proposed approach. This diagram is my interpretation of the tips listed in the discussion referenced above. The two questions I have boil down to:
If the firmware mods are required, that will be a new field of study for me, and not really excited about deviation from the released code.
Any guidance appreciated.
