Ortur Laser Master 3 LE Quality Issues

Ortur Laser Master 3 LE Quality Issues

I recently purchased an Ortur Laser Master 3 LE . It worked fine for about a month and then began clicking when homing in the X axis. After initiating a support ticket it turns out the problem was simply poor Quality Control. I also had Quality Control issues with my Ortur Laser Master 3 that I purchased as well.

One of the claims to fame of the Laser Master 3 LE is that the X rail is preassembled. This simplifies, and speeds up assembly time. And herein lies the problem. It was preassembled POORLY.

Here was the problem:

X Homing Issues

Investigation Begins

The first thing I did was to test the X belt tension. It seemed okay initially.

Then I inspected the grub gear on the X motor shaft. I got an allen wrench and checked the tightness of the set screws. The set screw over the flat part of the motor shaft was simply free spinning. It wasn’t threaded or engaged at all. Sad. And poor quality control by Ortur yet again.

However, this wasn’t the issue. The other set screw was holding the grub gear firmly.

At this point though I knew I’d be wanting a new grub gear from Ortur. So I opened a support ticket. At this point any reader of my blog should know I’m not a fan of Ortur. I’ve had issues with the Laser Master 3 and now the Laser Master 3 LE. I was a huge fan of the Laser Master 2 and oddly enough I think the Ortur Aufero Laser 2 is a smashing hit and should be on the short buyers list for new laser users. It is simply amazing. If it is good, I will say it is good. If it is crap, I’ll say that too.

Despite the fact I think Ortur is not doing well that DOES NOT extend to their support Department. Their Facebook Forum is monitored by “Gil” and Gil responded within minutes of me submitting my support ticket. He was extremely helpful and agreed to send me the parts I asked for after we worked through the issue.

The Culprit Is Found

After looking at the X rail construction I went to tighten the block screw. At this point I didn’t realize it was NOT the tensioning screw. It was loose and when I tightened it the block began to level out. It was sitting at a slight angle. Tightening that screw increased tension on the belt which seemed to fix my homing issue. Until the next day when the homing operation failed again.

Here we go again.

Gil told me to loosen the X rail block screw then loosen and tighten the tensioning screw. You have to remove a cover to access this adjusting screw. Then I re-tightened the x rail block screw. However, the screw next to it free spins.

That loose screw holds the roller assembly to the x rail.

I removed that screw which wasn’t engaged at all. It was a 3mm x 6mm fastener. I replaced it with a 3mm x 8mm long screw and it tightens correctly now.


Did I Fix It?

I think so. I think the rail / roller assembly junction being unsecured may have been the driving force in this issue. Let’s review what was wrong on the pre-assembled X Rail though:

  • Grub Gear Set Screw stripped and free spinning
  • X Block Screw loose
  • Roller to Frame screw not correct length and not securing that corner of the axis.

That’s a whole lot of shit wrong on one component.

Ortur agreed to send me the following components for a more permanent fix:

  • QC OLM3L3 X Sprocket
  • OLM3L3 X belt tensioner


I simply cannot recommend to anyone to purchase an Ortur laser. While they were once the only real game in town they have been surpassed by literally every other laser manufacturer. While 40 watt lasers are becoming commonplace, Ortur can’t even get a 20 watt laser out the door.

I have had quality issues with my Laser Master 3 and now all of these issues I just recorded on my new Laser Master 3 LE machine have soured my opinion of their flagship lasers.

The only positive aspect of this was that Ortur Support was EXCEPTIONAL. My issue is not with Support but with the Ortur’s Quality Control which seems to be non-existent.

    Thank you for your post, I have the exact same problem and feelings (support is great, Gil helped me before).

    I will try to change the screw that free spins if I have the good one at home.

    I am having the same problem on the exact same model. How do I get in touch with Gil? I don’t see any phone number for tech support here in the USA. Thank you.

    I bought my Ortur Laser Master 3 in September 2023 from 4evatech.

    On June 18 2024, my x-axis timing / drive belt snapped. I started sourcing for a replacement belt and contacted you 4evatech on whats app, but did not get any response from them (how disappointing). I contacted Ortur self and they had a timing belt for US$20. Fortunately I got 2x belts from Amazon @ R428 taxes & duties included.

    While installing the new timing belt it came to my attention that the grub screws, supposed to keep the driving pulley in place on the drive motor, were loose. Keep in mind the x-axis bar is pre assembled and I did not have to do it when I assembled my machine when I received it.
    So when I replaced the x-axis belt according to instructions, assembled the x-axis bar and installed it, I was happy to find my machine was running smoothly. I did some testing first to determine if there were any hiccups. I started my project after feeling confident that the machine is working properly.
    To my disappointment after about half an hour I heard a screeching noise and paused the project to determine what was making the noise. To my surprise I saw the drive pulley moved downward on the drive shaft of the drive motor. I don’t understand why this is happening, for I did fasten the grub screws tightly. It seems to me the grub screws are not efficient for the purpose they must fulfill.
    I’m sitting in great despair, because I bought this machine to earn an extra income and now it’s more of a liability than an asset and I’m loosing money. I don’t know if you had similar complaints about this matter and if I am the only one complaining.
    It will be greatly appreciated if someone could pay attention to this problem on the machines and provide solutions as to how we can solve this.
    I bought the machine with accessories and now I’m starting to regret my decision. As I said I bought the machine to earn extra income, now it’s costing me my time and money.

    Extremely disappointed
