Is your quickswap (and maybe bracing kit) set in your machine and Luban correctly?
You have to set you work origin at preparing a new project (lower left corner in your case) AND before starting the job on Luban workspace.
You should run a boundary check before starting to see if everything is in it.
So when you run a boundary scan, does this align with the coin? If so: There is an offset between the red crosshairs laser and the actual IR laser point. For me, the offsets are correctly in the settings and my laser aligns good enough with the crosshairs. If your boundary scan is spot on, but the laser is off, it might be that your offsets are somehow screwed up. On the touchscreen, you go to Settings - 2W laser - Cross Line Indicator Offset. The values I have there (factory settings): X Offset 21.8, Y Offset -10.596.
And, something I do wrong very often: When I carefully navigated to the work origin, I forget to hit “Set work origin”… I run boundary, it is completely off and I have to find the spot again - always angry with myself then
