Both the z and x run off happen after the print is done. Perhaps 5 minutes later, while it is idling.
If I start a second print. it will usually run really slow and stuttery. It is like there is some leftover garbage. but sending cancels and other commands in the end code doesn't seem to fix it.. :(
None of this happened before I upgrade to this firmware. I did not change Octo. But I love the features. I just want to have end print and cancel print perform a soft-boot to clear out the crap.
