Quote:Will the AZ-EQ6 need 2 belt tensioners too? Why?
Ed Thomas Deep Space Products www.deepspaceproducts.com
Quote:Ed I see your point, but I still think 2 spring loaded belt tensioners should have been inside the AZ-EQ6 because the user doesn't know exactly when the belts come loose or even start to slip and the motors have to be moved to tension again the belts as you said but you don't know when you need to do it.The belt related problems present in iEQ45 I suppose will be present in AZ-EQ6 too because I don't have much trust in the quality/durability of those belts considering the "cut costs" desease present everywhere now.A spring loaded belt tensioner for each belt would have been the perfect simple cure in real time for this and increased PE without warning.I suppose a German manufacturer of such a mount would have payed more attention to such design details considering the AZ-EQ6 is not a cheap product these days.Ed, maybe your future hypertuning kit for AZ-EQ6 should contain those 2 spring loaded belt tensioners.
Quote:Why was the belt tensioner necessary for IEQ45?
Quote:Quote:Why was the belt tensioner necessary for IEQ45? It wasn't necessary, but it was a good way to reduce backlash inherent in the belt due to 'droop' between the two pulleys. One side of the belt is always going to have more slack than the other when the pulleys are a fixed distance, especially after use when the belt stretches a bit.The result is easily seen on the iEQ45 (and similar mounts) with the housing cover removed so you can see both pulleys.Marking the pulleys with a felt tipped marker and then slewing in RA left and right will show the delay in the worm pulley before it starts to turn when changing the direction of the slew.It's not a huge deal for visual, but for imaging, eliminating the delay (backlash) results in faster calibration in PHD when clearing DEC backlash and reduces correction movements when guiding.For those that like to tinker, here's my final configuration of the tensioner:4. V5 Angle by Astronewb2011, on FlickrThis mod works on early iEQ45s, iOptron is going to offer a fine toothed pulley and belt with their worm upgrade kit, and may be installing it on the current 2013 iEQ45. That fine pitched belt is extremely stiff, and may not need a tensioner at all?Hope the info helps,Paul
