Can I stick the LU2-10A on the Laser Master Pro 2, S1? (not the S2)

[ColeR (Cole Rinehardt)]

I have the Laser Master Pro 2-S1, Its has the laser module (LU2-4) on it, I’m wanting to upgrade it to the LU2-10A.

Everywhere I look, everyone is asking about the S2 version, I do not have the S2.

I asked on Reddit, and someone said the difference is the S1 is 12v and the S2 is 24v.

So how can I be running the S1 (12v) but be running the LU2-4 laser that uses 24v?

according to Ortur’s own site

Product Comparisons

I need to verify that I’m not pushing only 12v to a 24v module, would it even work, if that is the case?

a new circuit board is cheaper than a new laser module.

Thanks for any insite.

I’m assuming the data about voltages are correct.

Generally the laser modules have on three inputs. Ground, PWM and supply voltage.

In simple terms you supply the module with a separate 24V supply.

This comes with the LU2-10A module, according to the website. Use the 24V supply with the OUC2.0 board that uses the 24V supply to feed the laser module.

Make sense?

I swapped out the LU2-4 (24V) laser module on my OLM2 Pro for the LU2-10A last year. Although it wasn’t specifically labeled as an S1 (I bought it back in Aug. of 2021) it has the 32-pin connector. The issue I had was with the OUC 2.0 adapter cables that came with it. The LU2-4 (5.5W) has a male 3-pin JST connector into which the 3-pin JST female connector is plugged. The problem I had was that the adapter cable that came with the LU2-10A kit also had a 3-pin JST female connector (see picture below). I ended up making my own cable with male connectors at both ends so I could plug the two female connectors together. You can read all about my adventure here: Well, ain’t that a &!$@# - Community Laser Talk - LightBurn Software Forum. The other issue with the OUC 2.0 (at least the one I had) is that once the fan came on (when the beam comes on) it stayed on until you removed power. I ended up chucking their OUC and building my own. It seems that the OUC was back feeding 24V to the controller, so that even though PWM was 0V at the end of a job, there was still 24V present to keep the fan on. I’m hoping that either I had a bad one or Ortur has got the issue fixed. Anyway, long story short, it’s working now and I’m happy with it.

cool thanks for the heads up, i read somewhere that whoever does this will need to power adapters. i checked my set up again, the laser is 24v the board is 24v and the laser is 24v. i think i’m going order it and then figure it out. i’m sure the person who said 12v was just mis-informed.

[ColeR (Cole Rinehardt)]

thanks i’ll read up on your adventures swapping over to the other module. everything i have is 24v so i hope it should be straight forward.

so ya going to order it up..

thanks for the detailed reply.

No problem. Give a shout if you have any questions about my adventures in module swapping.
