I have run this file several times and there were several times it burns a extra space in the word Milk at the top. The burn is done using Offset Fill. For some reason it burns all the rest of the text then goes back and burns the K. I have tried sending the file to the laser and burning the image from the controller.
I have been able to successfully burn it a few times without the error. But the last 3 attempts have the same issue.
I am including the image but not sure if it will work or not.
I am hoping someone can tell me what the problem is.
Thanks
Hi Tim
I cant explain or resolve the issue but I checked previous topics under Missing text, Gaps in text…etc
The only thing that caught my attention was something said about Layers and seeing as how your K is the last thing done, Could the k be on a different layer.
Now why the gap, then the K…I dont know! but doesnt the gap have a similar width as a Capital letter?
Could the problem be in the Gcode…did you design that piece or download from somewhere.
Maybe if you can show the code and settings the problem might be visible to those who would know.
If it has burned ok previously, could it be a connection problem.
Thanks for everyone’s help
Here is the Preview of the file. It looks ok to me but you can see that the k is the last thing burned before doing the image.
I am not sure how to save the GCODE I have the option to save a RD file but It does not look anything like GCODE when viewed with notebook.
I am going to try to burn the file using all fill instead of burning text with Offset Fill to see what happens.
Even after installing the font, the “text” has been converted to shapes and is no longer editable. The C00 layer is set to Fill, rather than Offset Fill, and behaves pretty much as expected: full-width scans along the X axis.
Setting it to Offset Fill shows several long motions while filling chunks of the pattern, but the doc cautions:
Offset Fill is intended for designs with a lot of space in between graphics, to cut down on the amount of travel time necessary to fill large, hollow shapes. If that description does not apply to your graphics, it’s best to use Fill instead of Offset Fill.
Those letters definitely do not consist of “large hollow shapes”, so I think the old saying applies: If it hurts when you do that, *don’t do that".
With that in mind, the “k” seems to be done as part of the “3½ Cups Flour” and “sugar / salt / oil” block, all of which the photo shows are slightly misaligned with respect to the “400 Degrees” and “yeast” below.
This resembles other problems that turned out to be:
The controller’s file memory is just about full, causing all manner of odd problems.
A USB problem garbling that block of data on its way to the Ruida controller
Things to try:
Delete all the old files from the controller. The LightBurn doc has some suggestions or you can do it directly from the controller’s display.
If you’re using USB, switch to Ethernet. A lengthy discussion of some pitfalls will guide you.
Protip: use cardboard until you are certain it works, then do one more on cardboard just be sure.
Thanks
Burning the same image using fill works fine every time. I was trying to use offset fill because it shaved some time off the burn. However it doesn’t save any time if it doesn’t work.
I am going change my setup to use ethernet to communicate with the laser. I am currently using a usb hub to connect the laser and the camera to my computer. I am sure that is causing problems. I just seemed strange it was always the same character. Thanks for your help and the links,
In my shop my desk is not far from the laser its just that the cable has to be run up the wall, across the ceiling and back down to the computer. which ends up being about 30ft, too long for USB. I have been using a powered USB cable which usually works ok. But it looks like there may be some issues.
I have been thinking of installing a fan less computer with lightburn installed on it in the laser and using wireless to communicate with it using PC anywhere or VNC.
Anyone have any Pros or Cons for doing this?
That’s just asking for trouble, as far too many folks have already discovered. The trouble with powered USB cables: unless they’re powered at the far end (very rare), a USB port that’s already having trouble must now provide the power, too.
You must do a clean install from a known-good MS ISO to eliminate the janky not-quite-valid / keyless OEM Windows installation, which (in my case) required prying a valid MS product key out of the seller.
Then turn on RDP access, run it full-screen from your Comfy-Chair desk for design work and from the laser for setup & running the job, and you’ll never look back. Somewhat to my surprise, performance over RDP is Close Enough™ to in-person as to make no difference.
