Here is version 0.69.2 which uses the same calibration pattern as 0.69.1 with two bug fixes.
First we weren’t recomputing the center point after each time that that the new calibration data was sent…that was only happening with a restart. Fixing that should help the process to run more smoothly.
Second a bug with the move back to center at the end was making the machine move unexpectedly fast which was startling.

Edit: Note that like 0.69 this builds on itself so each run should get better than the one before it.
