Laser Master 2 and laser module NEJE 40W, will they work together?

#1

Hi ORTUR experts! I have an Ortur Laser Master 2 20W, but I want a more powerful laser. Can you please tell me if I can replace my 20W laser module with a NEJE laser module 40W.
Thanks in advance!

Yes, but you need a 12V4A power supply for support. NEJE’s latest Master 2s max supports a larger engraving area, is the latest 32-bit control system, supports app control, and 100% supports lighburn software. You can consider it.

I will answer my own question: the 40W laser module works on the OLM2 frame. To install the module, I made a small modification. The result is already amazing! Birch plywood (3mm) is cut in 1 pass at a speed of 100mm / 60-100pw. There are still more modifications to be made in the future, but I’m already happy with the result. It is a pity that today Orthur does not have its own 40W module.

I just have one question: you mention a 12V 4A power supply, I received a KIT with a 12V 3A power supply, is this normal?

Hello , i want to change my 20w module also , can you tell what modifications you did with cables or it was plug and play ?

  1. cut off the 3-pin connector near the laser module. and soldered two 3-pin and 4-pin connectors there (the temperature cable was not soldered)

  3. I also screwed the “extension cord” on the x-axis to turn on the Y limit switch.

Hi can you draw a rough diagram on which wires were cut and what went to where. Please I just bought this and can’t figure it out and which power supply did you use

Having examined the mainboard connection diagram

If your circuits or connecting cables are different, then check on your devices

Going this fought do you still need a power supply or can it run straight from the power the main board produces? Thank you so much by the way.

#10

I bought the KIT from the link from my first post, it had a 12V 3A power supply. A power supply with the same characteristics was in my OLM2. As a result, I did not change anything, the laser module is powered from the mainboard.

You are a beast my friend thank you so much

Hello, I just wired my new 30 watt 4 pin laser like this to my laser master 2, all the lights come on the board, but still nothing from the laser?

#13

I cannot give you specific instructions, you yourself must check your cables and make sure that they are connected correctly.
If you show a photo of your cables and how they are connected, then maybe I can suggest something, but this is not accurate

These are the lights that come on when I hit the “fire” button on lightburn.

#16

The pwm light the only one the doesn’t light up when I hit the fire button.

#17

Black and white wire are mixed.

#18

I tried switching those wires around, still nothing.

#19

Have you tried to connect a laser module to a test board and check its performance?

#20

Yes I have, no luck. Originally I bypassed the board that has the home switch built in and the laser worked, just way out of alignment with x and y axis. Laser is running now with original laser, so I don’t think it’s a hardware issue.
