I’m finishing up the assembly of my X-Carve, and have no idea what kind of tension I should have on the belts. I picked up a little fish scale on Amazon and made the following procedure:
- On belt of concern, run the carriage or gantry all the way to the “secure” side of the belt (the non-adjusting end).
- Zero scale/tension gauge and hook under belt in middle of belt.
- With one hand holding a small ruler, pull up with the scale until the belt has been pulled up to the 1 inch mark, then read the gauge.
Right now, I have my belts all set so it takes 6 pounds of force to pull them up one inch. When I move the carriage or gantry by hand it seems to take a little force, but I’m not sure how easy they should be to move by hand. I also rechecked them 24 hours later and they were still pretty much 6 pounds, so they don’t seem to have been stretched too much.
Has anyone else done something similar to this for an X-Carve that is properly tensioned? Is 6 pounds too much tension for 1 inch of deflection?
For those interested, the scale is a [Mango Spot Digital Fishing Hook Hanging Scale]. It’s currently on sale for $7.99 on Amazon.
@PaulKaplan, this may be something your engineers could easily check and make into a tensioning procedure, once they verify what the proper tension should be.
