Here is the solution of how to solve MIRACLE A7 key cutting machine “Y sensor error” when it starts.
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.
