I’m running a 1300x900 laser bed on a Ruida 6442S-B(EC) controller.
LightBurn version 0.9.11
I discovered this error while trying to make a Scanning Offset Adjustment test pattern for speeds 100-600mm/s. My initial test had 6 vertical aligned boxes, each with it’s own color and increasing speeds and power.
After getting the error I simplified this for the sake of testing since I pinpointed what settings are causing the error. I’m now working with six 5x5mm boxes vertically aligned and in the center of my 1300x900 bed. Over travel and ramping are not the issue. All of the layers in this test are set for 1mm intervals so roughly 25 lines per inch, but the results are the same regardless of the interval. I’m also using 300mm/s but get the same results with other speeds. As long as the boxes are all the of the same color/layer the error does not occur. Once a new layer is in the mix, like the alternating black and blue layers, it causes the error.
In each of the following tests I selected a column and then Start to run the test. Here are the results.
First test, I selected the Left Black column, it runs fine.
Second test, I selected the Middle Blue column, it runs fine.
Third test, I selected the Right Black and Blue column, it starts at the bottom, runs the blue box, moves up to the next blue box and runs a couple lines then gives the error, “Not Enough Extended Space”.
The error occurs whenever Optimize Cut Path is Turned Off, OR when it’s turned On and set with Order By Layer.
The error does not occur if Optimize Cut Path is Turned On, AND Order By Group OR Order By Priority are selected. Adding Order By Layer anywhere in the stack will cause the error to occur.
I hope this is enough troubleshooting and detail for you to re-produce the error on your end and find a resolution. I was unable to re-produce the error in RDWorks but it doesn’t have the nice optimization settings that LightBurn has.
