Re: Dec axis motor system faulty or newbie error?? #EXOS2


 

Paul,

If the DEC axis stays put when the clutch is on, then the clutch isn't slipping and neither is the mesh between the worm and ring gears.
If you open the belt cover and the belt is moving, but the axis isn't, then I would think that the most likely cause would be a loose setscrew on the large pulley.
Easy to check and service if you remove the DEC motor cover, not much to it.  Notes below :-)
