Hi All,
As my first Zortrax has literally run 24/7 for 5 weeks straight, I want to give it some love when it's brother arrives next week.
I'm seeing some rubbing of the belts on the pulleys, and would say that they haven't been aligned correctly at the factory. No ill effects, but some wearing through of the belt on the edge that is touching the pulley.
I plan to go right over it and check all the pulley screws, align the belt pulleys a bit better and tension all the belts as required.
The videos are quite good, and I'm comfortable with all the procedures shown, but just how tight the belts should be is a little unclear. I see mention of getting a "tone" or something out of the belt when flicking it with the finger, or something like that, but I'd like to get a bit more scientific with it as I'll have 2 of them running heavily.
I'm assuming the longer belts are tensioned by the 2 protruding allen head bolts on the carraige?
Is there a tool or procedure for setting belt tension, I realize it's probably a general setting but I'd like to get them evenly tensioned at least.
Basically, how tight should I go, and how do I measure the tightness?
Cheers in advance for any help.
