I have a Sculpfun S9 (simple diode laser) and run (latest version of) Lightburn on my desktop and a laptop.
My laptop does as expected, my desktop has a problem: it will only move to negative coordinates. It will not jog (while on X=0 and Y=0) to the right or up, only left and down, so to -10, not to positive coordinates. Also framing a project gives an error As far as I can see, settings are the same on both machines.
Since my laptop works fine, I guess it’s not the machine but (a setting in) Lightburn on my desktop.
However, if you’d like to understand what’s happening it may be an opportunity to compare between the two computers to see what might be causing the issue.
It’s likely going to be under Edit->Device Settings. Based on symptoms it’s likely to be a difference in Origin setting.
Thank you. Still don’t know what was wrong, but both computers are OK.
I did export the settings from my desktop too, so I’ll look at it next year
Best wishes for 2024!
Hi, the export of the settings did not work. My laser was reacting really weird, on the laptop as well.
Finally I connected it to LaserGRBL and now everything works like a charm, also with Lightburn.
Maybe LaserGRBL has done a reset of settings in the machine, no ideay, but everything works great now.
The S9 has no limit switches; therefore, you can’t really work with coordinates. I guess you accidentally set LightBurn to use absolute coordinates, which does not work reliably then. It’s easier to use “current position” to start from.
Hi Miske,
I know the S9 has no limit switches but that doesn’t mean you can’t install them.
They are working fine for about half a year. Now that I’ve bought a rotary, it needs to work a little different since I can’t Home with a rotary. And for some obscure reason, my machine would only work properly after using the Home button.
I think there were some values stored in the controller. After I connected it with LaserGRBL, I think those values were cleaned because everything works now as it should.
I know you can install limit switches, though the lack of them most often confuses users, that’s why I mentioned them.
When using a rotary, you can’t use homing, of course, the y-axis has no limit then. There are no values stored in the controller that LaserGRBL could reset, but glad that it’s working again.
