Getting layer shifting on Dreamer
Recently started getting layer shifting on all of my prints from the base all the way to the top of the print. I checked and tighten all of the belts and pulleys, still seeing the shifting. Went to update firmware(running very old 1.4), and printer will not connect to computer(I always use sd card for my prints). Also when I start the machine the screen starts up in Chinese(just started happening). Can firmware cause layer shifting issues and is it ok to remove micro sd card from machine and install firmware that way?
Thanks
