Laser controller not following correct path

My laser is not following the path sent.

This is what I am sending.

This is what my laser is cutting. It is different each time.

Also sometimes the laser won’t cut at all and just sits with the timer clicking over.

Could this possibly be a usb cable issue?

Ensure you have the correct origin position specified in Lightburn. It must match your machine.

You can flip which quadrant it thinks it using and that will flip the image.

Generally these are already setup and this is beyond most users. Wondering how this ended up like this?

With a Ruida controller and a Mac, almost certainly “yes”.

Lightburn not cutting the correct shape

I copy/paste my paths from illustrator, and they usually work great, but today Im experiencing some cut paths that don’t match what I see on the screen. I can preview the cut animationm in Lightburn and it looks OK, but the actual cut is incorrect. [image] [image] [image]

Random Letters Missing During Laser Cut – Only Works Fine One Letter at a Time

Hi everyone, I’m having a strange issue with my laser cutter and I’d love some help figuring it out. As you can see in the picture (from top to bottom, it shows my first to most recent attempts), some letters are randomly missing or partially cut when engraving text. I’m cutting at speed 50mm/s and power 35%. I’ve already tried applying an offset, and then used the Pathfinder tool (unite/merge) afterward — but there’s always a small issue somewhere. What’s odd is that if I cut each letter in…

Thanks for this info. I have received poor after sales service from the company I purchased my laser from. They did not know how to flip the image so I just put up with it.
Onto the main issues, other forum users suspect that the usb cable may be the problem so I will get a new one tomorrow.

[Bucky-in-Oz (Wayne Buxton)]

Thanks Ed. I suspected as much. I will get new cable tomorrow and do some testing.

Did that fix the issue?

If possible use an Ethernet connection to your lan. This is much more dependable and doesn’t depend on anything other than a network connection, that you already have in all likelihood. No drivers or anything to mess with.

I have mine on a $12 wireless router from Amazon, the machines in the garage.

If you have a spare PI laying around, Lightburn has the firmware for their wireless bridge available, they also sell the whole thing.. It is better, handles UDP traffic better…

Perhaps there’s something deeper going on.

AFAICT, there are three “origin” settings that must match:

• The corner the machine homes at when starting up, determined by the hardware switches
• The LightBurn Machine origin setting
• The controller’s Screen Origin setting (as @jkwilborn described) should indicate the same corner.

The first two determine which corner LightBurn’s small red Origin marker appears in.

In Absolute Coordinate mode, that corner will also have a small green square marking the Job Origin.

If that’s not what you eventually ended up with, let me know so I can once again stop thinking I know something.

Image display sorted.
Thanks Jack

Glad it’s working.
