I assembled the moai 130 and calibrated it on the bench top and it functioned as intended. I then I moved it and over the course of 10 days it seems the calibration of the x/y got worse and worse. I moved it again and retested the yuan test and cross-section test. Now the laser trace is extremely elliptical, as the extrema in the x are outside the build area and the y is slightly too large. The cross-section test is about 1 cm displaced in both x/y from the center. I am worried that the printer is beyond repair and I am trepidations about attempting the fix (https://docs.google.com/document/d/17EYM9WTy9HMLh6x3lLFIOnQ_dxqDnTRWgukOVBkIxvg/edit)
has anyone used this procedure to fix this kind of misalignment. Both moves were done gently with no dropping of the printer or banging the case into things. It was not stored in an area with excessive vibration. Any advice would be appreciated.
