Thanks for understanding.
The most common mistake that beginners encounter is to run G code rashly without mastering the properties of the machine tool,which results in the main shaft of engraving machine hitting the bracket of engraving machine.
Therefore, it is suggested that the limit switch and emergency stop switch must be installed first.
If these protective switches are not installed, in case of emergency, in addition to pressing the emergency stop reset and turning off the motor power, the most convenient way to stop the
machine is to pull off the USB cable!
As long as you pull off the USB cable, the machine will stop automatically!!!
