Laser SIG: Ortur Help Session

As China reopened, a river of Ortur Diode Lasers flowed into our community.
These $200 lasers are pretty appealing but some have been challenged.
This was all about helping get more people across the finish line.

Hey there ,i got my 20w laser ,but im missing a cable its the x motor cable .
Can you please help me out,can`t use my laser,anyone know where i can buy this cable?

Comett, welcome to the community.
The simplest recommendation is to write Ortur.
We have one of their employees who posts messages here.

I’ll try to find his email and will post it to this thread.

Justin can be reached here:

I might be able to make you one but will have to check my connector supply to see if what I have matches along with the pin/socket sizes. Will post back tomorrow on this.

Thanks, that’s the best news I’ve got in a month please keep me posted

Do you live in Canada?

I live in Mississauga Ontario

You’re kidding right? San Diego Fine Woodworkers Association…

The cable is complete, you’re welcome to swing by and pick it up.

No I’m not I wish I wasn’t ,is there any way you can ship it to me?

That’s not very nice, I was just looking for someone to help me out , but I guess you don’t care, I got this laser over a month now and trying and trying to get someone any one to help me out

I purchased this laser from AliExpress, the same day, the seller said that he was going to ship me out a cable connection but no cable.
I’ve tried to contact ortur, but they don’t reply to my email.
I’m not a tech guy.i I don’t know this forum was for San Diego only I just wanted some help.I’m new in this laser world as you have noticed. and once I get this cable god willing I’m going to need more help.

Hello there, I’m needing help with my Ortur Laser Master 2 15W laser please. I’m able to operate my laser at less than 450 S value max with great results however if I set it above 500 it barely moves and the laser shoots in burst and the result is a very small burn awkward shape. I’m using Laser GRBL. I’m using the power supply that came with the laser from gearbest. It’s a 12V 5A output. Any help would be greatly appreciated.

When you say “450 S value max” what exactly do you mean? We here tend to use Lightburn as our control software so if that’s a reference to LaserGRBL then you’ll need to explain what that input variable represents. It doesn’t ring a bell and I’m not sure what the equivalent is in Lightburn.

I’m sorry not S value max I mean the S-Max. I’m new to this and this is my first Laser from what I gather from reading the manual is the S-Max is the power setting of the laser. 1000 S-Max is using the laser at maximum power and 500 S-max is using the laser at half power.

$30 should be 1000 and generally you don’t change that and instead you vary the power in your application which generates your gcode.

I think ortur uses the same 32bit controller and firmware on their Laser Master and Laser Master 2 products and if so, this is what my configuration looks like and the only thing which would be different is the bed size and maybe end stop settings.

$130 and $131 are the bed dimensions.
$30 is your S-Max and as you can see, my Laser Maser/LM is 160x150 and S-Max is 1000

I replaced the power supply and successfully ran the laser at 100%. The original power supply must have been defective.

Hi - I’m not in San Diego, and I don’t work on wood, but I found your video above on YouTube and I wanted to say thank you all for putting up such a detailed troubleshooting video.

I bought an Ortur laser a while ago and have only been disappointed with it - I picked up the lab stand linked in this thread, and I hope to be able to finally be able to focus the laser correctly.

Cheers,
Ry

Ry, if your questions aren’t too demanding then feel free to ask them.
We’re a community of enthusiasts and we think lasers are fun!
Just post your questions and we’ll see what we can do.

Thanks. I have it etching anodized aluminum, which I couldn’t do before. The lab table should be here today, so I’ll be able to have even better control over focus.

The keys to etching anodized aluminum are:

  1. Focus
  2. Appropriate art (well formed SVGs, laser cutter fonts, the like)
  3. use a color that contrasts with the laser
  4. or coat the aluminum in black sharpie.

I’m working on tests to see what speeds and feeds will work best, but using the sharpie seems to be key.
