Telescope encoder or no telescope encoder?
#question
Hi Frank, Friction drives can slip, but depending on the design and the materials used, they may not slip. Mesu Mounts are a good example of a design that seems to work well - my understanding is that

Cable Management on HO Ultralight 16" Dob
#question
Hi Markus, It is better to have a bit of slack rather than too tight. I presume you do not have one of the newer mounts that have the cables going through the axis. My own experience is from 2008 to t

#question What determines azimuth in SiTechExe?
#question
That is, indeed, the behavior I expected, but it does not seem to be what I'm observing. For example, I synced to Segin (epsilon cass) a few minutes ago. At my latitude, azimuth should be about 331 de

Hi Mark, v3.9 is a servoI firmware version I think. I think you are using a fairly recent version because of one of your prior posts. In the numbers tab, the alt and az are the actual altitude and azi

Hi Bill, As Bill G mentioned, Sidereal technologies sells cog belts and pulleys. Also you can get almost anyhting mechanical from McMaster-Carr at https://www.mcmaster.com/ Running SiTech at 12 volts

OK Don, thanks again. I understand what you're saying. So you would recommend running this at 24v with the motors I do have as opposed to 12v, is that correct? Also, I'm clueless where to find these g

The shaft encoders are for manual drag/track, the motor encoders are ignored. The motor encoders are for slew/track, the shaft encoders are ignored. It's one or the other. The servo's are not slipping

I don't see any reason why you can't clutch them. On the other hand you will lose your sync with the sky. I used this system with a GEM C-14 and moved all over the sky (with a script) as many as 50+ t

Thanks Jim. Can you clutch these things? I jump all over the sky so I’d like to just grab and point then let the tracking kick in.

Wow thank you Don. It’s going to take me a few weeks to digest this LOL. I’m sure there will be follow up questions but I am impressed with your knowledge 😁
