Tilt motor made a weird noise, now won't home
Posted: Fri May 24, 2019 2:47 am
Last night I put a print on before going to bed, homed alright and everything seemed fine besides it made a low brrr noise one of the slices during print but the noise stopped.
In the morning I came down to find the print failed with everything was stuck to the film.
Suspecting it may be the tilt stepper motor in the 'setup' menu on contour I tried to manually move the tilt motor with the +/- buttons and it would make that brrr noise and the quartz would jitter but not really move up or down nicely. Just jitter and stay on the same pitch.
I came to the forums and found a few posts with similar problems where restarting contour, unplugging the printer and USB cables, reset etc etc were recommended
I did this to a T:
"To fix this, please turn off the power from the back, and turn the long Z screw by hand until the arm is up about half way. Exit the Contour software, unplug the USB cable from the back of the printer and press the little reset button next to it. Then plug the cable back, turn on the power, open Contour and run the home cycle again. Whenever running the home cycle please make sure the build plate and the resin tank are completely removed."
After doing this the first time I tried to home the Z arm went down and touched its sensor fine, then the quartz plate went down all the way fine and with virtually no noise, then nothing.
I tried the power off reset thing again *with the quartz plate still down* and the Z arm came down fine, then the quartz tilt motor sounded like it was trying to pull the plate down more but couldn't as it was all the way down already, so I pulled the power, opened it up, un mounted the stepper motor to the tilt and rotated it until the quartz plate was back to it's up and level height, and did the power off, reset thing again.
Now the Z arm goes down then nothing.
I've tried multiple times, restarting the computer etc, nothing.
What do I do now?
Note: I already have the tilt motor upgrade and am running Countor v. 1.9.38.0
