@phaedrux I had a long conversation with Steve from SeeMeCNC and he suggested I roll back from RipRap version 3.3 to 3.2.2 and follow his service manual guide: https://docs.google.com/document/d/1IQf191FP7EgV8IRpa__jZviF_lfd1jcKVwHD2J7U9pw/edit
He said he's tested this instruction set on over 100 different brands (he might have been exaggerating a little). He cautioned me that there are a few redundant steps, flash the FW, make a change, and flash it again. He said doing that was important. So tomorrow, I'm going to go through his instructions and follow every step.
If/when I hit the issue where the Duet wifi server fails to initialize again, I'll send you the M122 output. With any luck rolling back might address that.
