Pretty annoying that the center work origin on the laser bed is off-center by 6 to 10 mm in either direction. So, constantly, I have to either move my SVG object in Luban, or move the wood over on the bed a few mm’s.
I chuckle every time I see that little metal nametag that came with the machine. Yeah, right, as if the machine is precise enough to properly space anything I engrave upon that. I’ve actually thought about making a replica tag in wood and experimenting on that, instead.
So, again… is there, maybe, a permanent Gcode prefix that Luban can store? Or a physical printhead adjustment that I don’t know about?
For those that have a crosshairs laser (20W, 40W and IR), you may need to correct the crosshairs offset to the actual laser aperture - can be set in Luban.
I don’t know what it means to “correct the crosshairs offset to actual laser aperture” in Luban. Where? How? Will I have to set that for every project?
The machine is plenty accurate if set up correctly. However, the aim and pray method, or the camera without parallax compensation is absolutely the wrong way to do it. You need to set up a repeatable origin, which is easiest in Lightburn, but you can back-hack it into Luban.
