Congratulations on the pull request @schmittjoshc

Now we need to decide as a community if we want to integrate these changes. You should vote by giving this comment a thumbs up or a thumbs down. Votes are counted in 48 hours. Ties will not be merged.

I'm just a robot, but I love to see people contributing so I'm going vote thumbs up (but my vote won't count...)!

Does this PR require that the matching firmware PR be already installed? I'm running the present MAslow v1.28GC crashed on the "Push to machine" step after running the holey calibration sequence:

If this is true, this PR should be closed now and re-opened after the firmware PR is opened.

As posted in the forum, some work needed before this is ready to merge. Closing this to prevent premature merging. I suggest opening a new PR with the repaired version as the robot seems to work from the time the original PR was opened.
