I am relatively new to Ruida and Lightburn. I came from Full Spectrum and will never look back.
There are some things that confuse me from time to time though. This latest is that I tried running a “Fill” job on my 90 Watt laser at 16in/sec @ 100% power and it kept giving me an error on the controller “Not enough buffer space”. After an hour of troubleshooting my cable, and bridge, trying USB, etc. I changed the speed from 16 in/sec to 15 in/sec and it worked.
First, what causes this. Secondly, is there a way to know what the max/fastest settings are?
16 inches per second is fast. There is probably not enough room on either side of the project for the laser head to slow down, change direction, then speed up again. Faster is not always faster.
When in fill mode the laser starts moving to get up to speed before starting to fire, then when it gets to the other side it has to slow down and reverse direction and ramp the speed back up again. Your controller takes the speed desired and calculates the space needed for those actions and if you’re workpiece too close to the edge of the bed it sets a warning. Try moving your workpiece away from the edge and see what happens.
If you look in the preview window and turn on show traversal moves you can see if it goes beyond the extent of your work bed. See below. The shape is within the work area, but the laser needs more space than is available to turn around. The green line is the work area.
Those are tucked away under Edit → Machine Settings → Vendor Settings for the X and Y axes.
Most likely, they’ll be about 500 mm/s = 20 in/s.
Although you can set any layer speed you want in LightBurn, the controller will limit the actual speed based on its configuration settings for the axes.
I’m rather surprised at this error, usually it’s indicative of low controller memory, but your description fits overscan. They kind of go off their rocker when they get low on memory.
I can run 1650mm/s which is about 64in/s – his 16in/s is about 400mm/s. Capable. I’d suggest keepin the speeds down anyway as there are other things happening that need to to react.
If you go into Edit → Device settings → additional settings… might need to read from the controller these are you settings. Mine are fast compared to most, so don’t change yours.
You can modify them from the Edit → Machine Settings. Suggest you save a copy of these factory settings before you modify anything… easy to get these confused…
