This post shows you how to do cutting calibration for a 2m2 Tank CNC Key cutting machine.

1. Connect the machine by Bluetooth.
Turn on the Bluetooth switch, then click search again.
Click "Bluetooth number".
The Bluetooth connection is OK.
The green color is a successful connection.

2. Cutting calibration
Click [Device Information] >> [Cutting calibration].
Please confirm the cutter is 2.0mm on the machine.

We followed the instructions in the APP and used the HON 66 key blank to calibrate.
Align the tip with the first line.

Don't remove the key.
Please clean the clamp and then click "OK".

Cutting calibration is finished, when next time for cutting calibration, this key blank can be used again, at least 6 times.
