solution by uobdii engineers:

A7 machine power off

Push the Y axis with great efforts, as much as you can

The copper pin is stuck in the track when the Y axis cannot be pushed anymore, so that the Y axis cannot go to the proper place

 

How to do Y- axis origin calibration:

All keys are cut with origin to center of key in all “Miracle” key cutting machines. So the center of the key (the center of clamp (y-axis)) is set to the origin as seen in Fig below, and so precise set up of the center point, that is the center of Y-axis of the clamp is very important. If the midpoint value of Y-axis hasn’t been set up properly, key is cut being inclined to one side, which needs to be corrected by aligning the origin of Y-axis.

 

This step will not be needed in normal case because miracle-A7 calibrates automatically. The following explanation was given just for conceptual understanding on the calibration.

Note:

Switch-on means the key cutting machine uses the power in the battery. If you always make the switch on, then you use the power in the battery, which may cause the battery unavailable.

Switch-off means the key cutting machine works with power supply.
