Very disappointed to see that there’s a firmware issue that prevents me from running G1029A. I abandoned the 11x11 calibration attempt but would love to get that working eventually. Unless I missed a resolution somewhere?
Instead I just reinstalled my heated bed as was discussed in the above post and gave the cover a good scrub + ipa treatment. Looks like my first layer, while not perfect, is adhering quite well! Seems like the heated bed is quite sensitive to installation issues.
Thanks for the link @nweolu!
