I have recently build my SO3 XL and squared it up as best as i could. I did run a successful hello world, but i have notised that the x-axis make a vibrating sound on the first travel it makes after homing. It only happens when i use rapid position right after homing and when the carriage stops the sound is normal again. It sounds a little bit like the belt misses the pulley. I have removed the x-axis motor and made shure the pulley set screw is secured. I have tried with different belt tension and adjusted the V-wheels. Starting to get stumped on what to do next. Any suggestion anyone?
Mechanically that part is pretty straight-forward, please check:
and verify the wiring — also check that none of the drag chains and so forth are getting snagged, see: http://docs.carbide3d.com/software-faq/home-switch-troubleshooting/
If none of that helps, let us know and we’ll dig deeper.
I had exactly the same trouble. Just check the x step motor attachment . In my case , just Tighten screws with the Allen key ,was ok to stop the noise.
- I have now tried to remove the x-axis motor again to check the set screws. I have tighten them well and applied locktite to them.
- I have losened the V-wheels and tensioned them again as the instructions specify.
- I cant see anything getting snagged when it makes it first travel. Not shure what to look for in the wiring. It seem that everything is connected as it should be.
- I have applied tension to the screws that holds the x and z-axis motor
The sound is still there and i captured it on a short clip of video here: https://youtu.be/_jYvJ72IlQ8
I still cant find out why the sound is created.
Sounds like something rattling. Is the belt slapping against the rail as the carriage moves?
Could it be the drag chain rattling as each link settles in place?
