Once you power back on like @folgheraphilip states, run a calibration. Whenever I mess with the firmware, I always redo the built in calibration. I have been happy with the 1.5 firmware that from back in May. Took the leap to the 1.6.00.00 and all is good so far. Haven’t printed any large items but a few plates worth of smaller items. I haven’t done the most recent small patch yet… Usually if it aint broke, i don’t mess with the firmware, but there were some features i wanted to take advantage of.
