Bed Leveling/Adhesion Issues for the Dual Extruder

Back to square one. Re-installing my bed while it was heated worked for a a few prints, but issues have resurfaced and I’m now unable to print again even when I re-try the same calibration routine. My guess is that when I get lucky and get a good calibration, I can print for a while on it until it slowly gets out of calibration. This is deeply frustrating, I don’t understand why it’s so hard to calibrate the dual extruder. My print isn’t even that large as you can see from the screenshot.

I’m definitely going to pursue that 11x11 firmware mod, although I forgot I’ll be travelling this weekend so can’t work on it for a week. Does anyone have any suggestions for trying to analyze and collect data on my bed level? The octoprint bed leveling mod looks like a good solution even though I have no experience with octoprint.
