for some reason my jobs keep stopping when the X axis spins to next position, its giving me alarm:82 and feedrate error
ive done this job many times and now its just stopping when its moving to next position
hopefully ive attached a screen grab of what its saying
This is the feedrate error
Hard to say for sure but this looks like some sort of communication issue. Check your cabling, maybe change USB ports. Have you introduced any new hardware to the computer or any other electrical devices near the laser that might be creating electrical noise?
nope not changed anything and tried using 3 different USB ports, only software change was the update to lightburn I think ive fixed it by changing the x-axis feed rate, it was set at 5000 so set it down to 2000 and ran the job without firing laser and seems to have worked
I suspect it’s a coincidence that the change would have resolved this. Error 22 is about a g-code syntax issue that wouldn’t be affected by a GRBL speed change.
LightBurn is very good about producing good g-code so if there’s a syntax issue that pops-up like this it’s usually from g-code being inserted through the pre/post g-code settings in Device Settings, the result of using the wrong device type, or due to a communication fault.
Glad you’re able to keep moving for the time being.
May I ask which GRBL communication protocol you selected in LightBurn. The iLaser protocol was updated recently and several folks that were using it for Grbl 1.1f began having syntax errors.
eeerr the short answer John is… not a clue, im not that savvy and it took me ages to find the feed rate setting and that seems to have fixed the problem, it seemed to only occur when there was a large gap between cutting parts, as it moved quickly to the next component it was almost like the stepper motor couldn’t take it once it sped up a lot, now just need to figure out why I get “out of bounds” warning every time
