Device is starting, please wait…
Device keep moving after connected.
Device makes a lot of noise, like “kakakakaka” “konkonkonkon”
Possible reason: Homing switch not trigged at homing end.
Solution: Normally, after connected, device will perform an homing cycle, motor will carry the laser module to rear left corner(where is rear left?) and stop at rear left cornor quietly, It may take 3~15seconds to finish homing, but sometimes homing failed, because the homing function depends on two buttons(limit switch), the button should trig at end of work range, If for some reason, the device can’t trigger the limit switch at the end of work range, device will keep moving and make “kakakakaka” noise. OK, now please check whether there is anything strange that prevents the limit switch from triggering at the end of work range(maybe is wire or something else).
Please check the limit switch on your device. Press the limit switch with your finger, it can be pressed and bounced normally. Try to move the laser head to home location manually to see if the limit switch can be triggered manually.
If the problem is not solved, please contact us.

Laser can’t burn on material
Possible reasons:
Set burning time too short —> set burning time at 10 mS
Set laser power too low —> set Laser power at 100%
Material is not suitable for burning —-> Change material is easy to burn, like Kraft paper
