It should use the machine’s origin point, if you’ve set the ‘Start From’ setting to ‘User Origin’. You would need to jog to the origin you want and press the Origin button on the controller. If you have the ‘Start From’ setting set to Absolute Coords, it will always be positioned exactly on the bed as it appears in the workspace. (Keep in mind, you likely have more experience with the controller than I do at this point)
It’s not supposed to be there, and I’ve never seen this, though I have only the TL403cb to test with so far. Which model is yours?
