Why is the marking quality bad on my Dover Controller?
- M
  morganbarajasAug 7, 2025
  If the marking quality is poor (weak marking) on your Dover Controller, several factors could be at play. First, ensure that your marking parameters are suitable for the substrate. If power loss is less than 15%, check and clean the focal lens for any dust or oil. Also, verify the vacuum nozzle position, placing it as close as possible downstream of the marking. Confirm that extractor filters aren't blocked and the vacuum level is sufficient. Make sure the IP65 air pressure is sufficient and dried, and that the IP65 air pressure pipe is optimal. If there is no power loss, it may be out of focus or the marking parameters are not correct. Finally, adjust laser settings in advanced settings (power adjustment).

How to fix weak marking on Dover Controller?

  To fix weak markings on your Dover Controller, start by adjusting the marking parameters. If there's minimal power loss (under 15%), try these steps: * Clean the lens to remove any dust or oil. * Adjust the vacuum nozzle to be as close as possible downstream from where the marking occurs. * Check the extractor filters to ensure they are not blocked and that the vacuum level is adequate. * Confirm the IP65 air pressure is both sufficient and dry. * Ensure the IP65 air pressure pipe is in optimal condition. If there is no power loss, it may be out of focus. You can also fine-tune the laser settings in advanced settings (power adjustment).

What to do if the Dover Controller marking is weak?
- A
  Anna SpearsAug 27, 2025
  If you're experiencing weak markings with your Dover Controller, it could be due to several reasons. It might be that the marking parameters are not suitable for the material you are marking. A dirty focal lens can cause this issue if the power loss is less than 15%; clean the lens to resolve this. Also, ensure the vacuum nozzle is positioned as close as possible after the marking point. Check that the extractor filters are not blocked and that the vacuum level is adequate. Confirm that the IP65 air pressure is sufficient and dried, and that the IP65 air pressure pipe is optimal. If there is no power loss, it may be out of focus. As well as this, you can adjust the laser settings in the advanced settings (power adjustment).
