I have been cutting paper using OPEN PLANE mode because I need to do stitching of multiple graphics. 

(I have a conveyor but it doesn't support my low tolerance). Between two calibration mark cuts when I clicked on “Process” I just got a message saying: PLEASE REMOVE THE BASE PLATE AND MEASURE THE DISTANCE AGAIN. There is no  base plate with Open Plane mode so what is to do? I certainly rebooted the machine. Rebooted xTool Creative Space. Reloaded the project. Removed the paper and reloaded the material (restarting calibration) to no avail. Has anyone run into something like this?
