I recently upgraded to the latest Cura lulzbot edition 2.6 and updated my firmware on my Taz 6. Now that it is done, I immediately noticed the X Y and Z on the printers LCD screen keep changing to ?'s. So the X the Y and the Z go back and forth from the letters, to ?'s.
Why is that happening and what does it mean? This is the first time I have updated my firmware since I bought the Taz 6 in Nov of 2016.
Thanks for any help.
