Hi posted this on face book a few days ago but no one could give me any ideas. My prints are being stretched in the z and I cant work out why, this seams to have started near the end of a print where the end of a tank barrel just kept going, now all prints are doing this. Its as if rather than the 40um my prints should be at the printer is doing 2 times the layer hight but following the x and y as if it was only 40um. Things is have tried, 2 brand new SD cards, changing the SD card reader on the Moai, uploading new firmware, levelling the bed(could not hurt), resting all settings to default. re-sliced all files, downloaded pre sliced files, checked files on SD card with cura and ideamaker.
here’s some photos 1 is the last print, 2 is the bed level calibration, 3 is what 1 is supposed to look like
