Cloudray LiteMarker 5W UV Laser no framing visible

[chrisnob (Chris Noble)]

Hi,

First time posting because I’m completely out of ideas.

I have a new Cloudray LiteMarker 5W UV Laser and it appears to be setup correctly in Lightburn. I am able to engrave things OK.

However, when I try framing I cannot see any preview from the UV laser. I have tried various materials, turning off all the lights just in case the preview was very dim but I cannot see any kind of framing.

I did search the forums but I could not find any posts to help. Same with a Google search, I’m out of ideas.

Am I missing a setting or am I misunderstanding how framing works on Galvo UV Lasers?

Thanks,

Chris

UV Galvos also have an assistive red dot for framing.

Post screenshots of your Device Settings, please. Especially the “Ports and Laser settings” tab.

Did you import the correct markcfg7 file? When I imported the one from the UV-5.zip file here, it adds a device with CO2 as the Laser Type, so I’m not sure, that’s the correct one.

Hi Aaron,

Thank you for the reply.

I did import the markcfg7 file that came on the USB stick with the laser. It initially set the device type to CO2, which I changed to UV.

Attached are my device settings.

Cheers,

Chris

Hi Aaron,

On my particular laser the red dots is purely for focus.

It consists of 2 red dot pointers on the front of the Galvo that come together on the piece when the focus height is right.

Cheers,

Chris

Hi Aaron,

Thank you for the pointers.

I think I have resolved the issue.

I setup my device again and reimported my markcfg7 file from the USB.

I tried various values for the Red Dot and a value of 5 shows the framing correctly.

Thanks again,

Chris
