File invalid, unknown file

Make sure the file is in RD format exported by RDworks or Lightburn.

If the file is already in RD format, you need to upgrade the mainboard firmware.

Machine protected

The cover proximity switch is failing or disabled.  Follow the steps below to troubleshoot.  

1. Enter the main interface on the control panel.

2. Place a piece of metal on the sensor to see if the protection sensor in the machine status interface has been triggered normally.

• If it has been triggered, adjust the position of the switch to where it can be triggered by the cover.
• If it isn’t triggered, check the switch’s wiring on the mainboard. If the wiring is not loose and disconnected, replace the switch with a new, identical one.

Water error 1 /cooler error

Something is wrong with the water protection.

 If your machine comes with a water pump or built-in water cooling system,

1. Check whether the water flow direction is correct (the outlet of the water pump MUST be connected to the water inlet of the machine and the water outlet of the machine MUST be connected to the inlet of the pump)
2. Check if the water pipe is clogged, bent, or knotted.

If there is no abnormality with the pipes or water flow,

1. Short the water flow sensor.
2. If the fault is eliminated after shorting, replace the water flow sensor with a new, identical one.

If the fault still exists,

1. Short the WP and GND ports on the laser control terminal of the mainboard. (as shown in the figure)
2. If the fault has been eliminated, then the wiring of the water protection system is problematic. Check the wiring.
3. If the fault persists, replace the mainboard with a new identical one.

If your machine does not come with a water pump, but has an OMTech chiller (generally used on models with a 1000×600mm or larger workbed)

1. Connect the chiller and the engraver with the provided signal line (as shown).
2. If the signal line is securely connected and the chiller does not sound an alarm while the machine does, then short the WP and GND port on the laser control terminal of the mainboard (as shown).
3. If the fault has been eliminated, then the wiring of the chiller is problematic. Check the wiring of the chiller.
4. If the fault persists, replace the mainboard with a new, identical one.

If you are using a chiller of a different brand, consult the chiller sales staff about the signal output. Alternatively, you can turn off the water protection function within the software (as shown), but this will potentially have the potential for damage to the laser tube caused by leaving the chiller on.

We do not recommend cooling the laser tube solely through a water pump unless the water temperature can be controlled within the recommended temperature range. If this is achievable, it is also a must to have water flow sensors, connected to the WP and GND port of the laser control terminal of the mainboard. They will stop the laser in case of abnormal water flow.

Water error 2 /cooler error 2

#2 laser tube water protection fault. First, check whether the machine has 2 laser tubes. If it does, see "water error 1" to check the water flow of the second laser tube. If it doesn’t, restore the factory settings(click).

Or enter the manufacturer's settings and disable Laser 2 can be through the RDWorks software,

1. Make sure you are using the latest version of RDWorks software.
2. Enable autofocus from the user parameters interface, (as shown).
