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 individually, it works perfectly every time. But as soon as I send a block of text, I always get one or two letters that don’t cut properly.
Has anyone encountered this before or have any ideas how to fix it?
For a Ruida controller, this is almost certainly due to a communication problem causing a loss of commands & data between the Mac and the controller.
If the machine is connected to the Mac through a USB cable, then this is definitely a communication problem.
Although you can try a known-good / high quality USB cable, using the controller’s Ethernet connection is generally the best way out. The doc covers the basics:
This discussion of a similar problem has some details:
While waiting, I did some more tests but couldn’t fix the problem…
Why does it only happen with this project and not with other files I cut?
If it was the cable, I’d probably see the same issue on other cuts, right?
Could it be a problem between my font and LightBurn? I feel like the issue started after the last update…
Just wanted to give an update in case it helps someone else!
I tried using a different USB C cable, but unfortunately that didn’t solve the issue. I then went out to get an Ethernet cable, followed all the setup steps carefully… and it works perfectly now!
A huge thank you to @ednisley for the help and guidance — I really appreciate your support !
There’s one more thing to check before doing the happy dance: configure the router so it cannot assign the Ruida’s static IP to another device on the LAN through DHCP.
If the PC and the Ruida have a direct connection, without using a LAN, then that doesn’t apply, because there is no router. However, if it’s on a LAN, this detailed discussion covers the problem:
My Verizon router has a simple way to set the DHCP IP range, but other ISPs / routers make that impossible. Let us know if you run into trouble, as somebody around here may have roughly the same setup.
Thank you.
