I have a Shapeoko XXL with a JTECH laser installed on it. After running a homing cycle when I Move the laser and save the position then try and move to that saved position the laser heads for home. The saved position worked before.
Homing on the Shapeoko sets the origin to the rear-right if I’m not mistaken, and you have to set the workspace offset to move the origin to front-left first. Usually that’s done with a macro: https://lightburnsoftware.github.io/NewDocs/CommonGrblSetups.html#shapeoko-xcarve-and-other-negative-workspace-systems
Ok but I never had to do that b4.
You only have to do it once until you move the zero point, which you’d do constantly if using it in CNC mode, and basically never when using it as a laser. You might’ve done it once and completely forgotten until now if you’ve only been using it for laser stuff for a while. It’s always been necessary with CNC machines with added lasers.
Ok, thank you. The manual reference makes sense to my problem.
The macro sets a known offset, but it’s equivalent to just jogging the laser to the front-left and zeroing by typing G92 X0 Y0 with it there.
