Received the item fast, and it’s doing the job. I’m planning to incorporate it into a rotary axis setup for a DIY CNC mill. The gearbox feels tight, and from what I can tell, there’s not much noticeable backlash. Everything looks good so far.
Thanks for you positive feedback, if you have any question, please feel free to contact us.
