“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe
Quote:Indoor false alignment multiple times over the past year at 22.5° Celsius, everything works fine as it should, never any errors. Bring it outside and let it adjust to spring time temperatures approx. 8° Celsius, cool down time is 2 hours. Receive a no response 17 error upon slewing to first alignment star.
Quote:What purpose does this transparent sticky tape serve on the board? Is it just to protect the joints?

Quote:Have to say, a number of the header solder points look weak / poorly done. Ideally, they should all look clean, well dressed. If you have the PCB work experience, I'd redo all the header PCB contact points just to clean things up and save some time, by not having to find the cold joint by trial and error. 15 minutes with the right iron and solder could solve the problem. The intermittent contact could also be caused by a poor cable connection in the plug assembly. Good luck.

Quote:Power cable connection is already quite snug, spreading the pin might make it difficult to insert.

Quote:You have to buy the boards from Celestron. Stan
Quote:Third part from whom? Celestron does sell MC boards IF that is his problem. Which it is likely not.

Quote:Yep, missed that this was an overseas customer. Good part is that it's likely a power problem, not a motor control board.
Quote:Or just spreading that silly pin.
What some may view as an argument I view as a different perspective.
Quote:On the other hand, when he spreads the pin and it doesn't work, he'll have lots of alternative possibilities for a fix. It's easy to try in any case. I give pin spreading a 50-50 shot in this case, but I would have tried it before pulling any boards since it's so easy to do.

Quote:Out of curiosity, you mentioned using multiple power sources. Can you please describe them? Also please describe the cables you're using to connect the battery to the mount (if you have more than one).
