Hi I seem to have an issue with lightburn.
I am running an engrave project that hangs 5min into the run on a Co2 Omtech 747.
I have previously run this image with out an issue.
I have changed formats from stucki to dither and to greyscale all with the same result.
It starts firstly doing erratic movements then just stops and i have to shut lightburn down to get any access.
Have anyone else had this issue ?
Have you checked if there is enough space in your controller? Nb. are you “starting” or “sending” your jobs to the KT32N?
I use start in lightburn for all my projects very really use the send function
It was just a question, I do it the same way as you.
But have you checked if there is enough space in the controller, they don’t like to be almost full.
The file you are trying to send is 89 Megabytes, so rather large. What is your DPI set to for your Image in LightBurn? That’s likely the issue, and lowering the DPI will reduce the file size you’re trying to transmit. Just a thought.
And is, probably, larger than the maximum 96.3 MB available in a KT332N controller with any other files / data:
Many thanks for the suggestion will lower it and give it a go. Was at 254 DPI.
Can you upgrade the memory of the KT332N controller ?
As far as I know, the memory is soldered in and isn’t user up gradable. Doubt it’s up gradable at all.
Most co2 machines have about a 0.20mm spot size with a 50.8mm lens (2"), so you might want to try an interval of around 0.20mm (127dpi) as a start for scanning operations.
I have the same controller and it is not upgradeable, just like @jkwilborn writes.
On the statement about the spot size in the same post I can say for my machine that it has, with the mentioned configuration, a smaller spot size.
In the picture you can see a line spacing of 0.2 and 0.1, in fact you can still see a clear demarcation between the lines even in the example with 0.1 LS.
So when I engrave images I am not above 0.1mm LS if I want the best result.
Hi Jk,
Thanks for the info greatly received.
I have reduced the size of the image and reduced the DPI to 210.
The transfer / sending window is now down to
But still have the same issue when using greyscale.
This is what appears after i press start i don’t use send.
At what point is using or with this sending of a file to my CO2 too much in Kb’s, how small does the file size have too be?
I have never had this issue before, if my CO2 is running out of flash memory is there a way to remedy.
Has lightburn now taken up more of this flash memory with this latest version 1.7.08??
Is it possible the firmware is the issue with my controller?
I assume you are usb connected?
Have you tried to use send instead of start? You have to run it from the machines console.
Does the machine start to run at all?
Reading the Ruida file list with Lightburn shows what?
I’ve only had issues when there are a number of files on the machine. In order to know, you’d have to look up your controller and how much room it has on it. Many times that’s shared with the devices firmware.
No.
