Reading again… I don´t know why I think this is going to be a case of that many calibrations that the machines goes crazy. Too many calibrations doesn´t work. You only need to:
- Reset calibration
- Be sure you print a calibration sheet scaled 100%
- Be sure the reading marks are well printed. If you’re not sure, go over them with a black pen
- Avoid dule and excesive lighting and glossiness in the reading marks
- Perform the calibration up to three times. Even if you see any line not exactly accurate, if you keep repeating the machine goes crazier and crazier. If this happened, reset calibration and do it only with 3 calibrations… ok 4 but you risk start worsening it.
- In that moment, after the 3 calibrations, perform a print then cut test with regular paper and something as my previous template. It should work. But if it doens´t at least you can take some useful conclusions from how it is doing wrong. Does the offset error go further and further as the shape is more far from the upper left mark? That should be due to a bad printing scale, for instance…
Hope this help you to begin to amending the process or/and show us results to help you reach conclusions
