I have been using lightburn to run my Ortur LU1-4 laser with good sucess. I recently upgraded to an Ortur Lr4 1a laser.
Lightburn will not recognize this laser , but will run the gantry and the activate the laser, however - my laser just has VERY low output. I have tried all the trouble shooting videos etc- Lightburn shows a LM 2 laser in settings.
I have looked at the $30 values and they are set to 1000 like the video suggests
If there is any way someone could help me with this I would greatly appreciate it. I am not sure where else to go for help and my laser is not operable.
Thanks so much
Aaron
You replaced one 20w blue light laser module with an infrared 2w module, and now you expect a similar output?
I am pretty sure [1] you will get very different results on the same materials, and [2] the focus on an I.R. laser is very, very, very critical.
Do you have the connection diagrams for both laser modules?
How do you know it is low output? What is your frame of reference?
Lightburn does not recognize any laser module. It only recognizes and talks to the laser controller board. What you hang on the trolley, which hangs on the gantry, makes no difference to Lightburn.
P.S. Welcome to the Lightburn Forum. You will see this Forum is a goldmine of information and help.
Low output as in wont leave a mark on cardboard at 100% power.
I have tried different height settings to optimize focus, the laser seems very dim although the point does seem small and focused.
I “upgraded” to this laser as Ortur told me it was capable of etching metal while my blue light laser was not.
Thanks so much for the resonse- Ortur has been good to help by email , but responses are slow and it is frustrating not being able to talk to anyone.

That might mean that it’s also not great at marking other materials though. Have you tried putting metal underneath it?
Different materials absorb different wavelengths of light. A typical fiber laser has no trouble burning away metal, but will struggle to mark normal white paper. A blue diode cannot easily mark glass or clear plastic, but a CO2 laser does it easily.
