Re: Threads problem
Yeh, when I look at it these are definitely the Gemini servo cover standoffs because the #492 standoffs are a lot longer in length.? But they all use the same 6-32 thread though.

Re: Threads problem
Maybe motor cover standoffs for the #492 steppers or Gemini servos?? I have both and they seem so familiar..

Re: Servo motor optical encoder replacement
Agree with David - didn't see his response in time :(.? these are $27 in the US, but after shipping and VAT, probably best to purchase in UK.

Re: Servo motor optical encoder replacement

be aware that you may also have damaged the main board axes PLD encoder IC. ?It reads these encoder pulses and compares them and switches between 1x and 4x resolution mode.
just sayin.

Re: Servo motor optical encoder replacement
You can replace with HEDS-9100#F00 or HEDS-9140#F00

Re: Gemini Motor Mounting Damage?
Hi James,
My guess is that it is a coincidence and there is nothing wrong with the actual hardware based on the fact that it slews and GOTOs fine.
Maybe you should look at the system that's NQR.?

Servo motor optical encoder replacement
Hello Group,
I have a problem with a runaway SVM-HT motor on my Gemini 1 L4 G11 mount. Basically when I turn on the Gemini, the motor just runs away at full slew speed. It got very close to disaster

Thanks Chip,
My G11 is the CG11, when Losmandy and Celestron combined their product offering way back when.? When I ordered my Gemini 2 also got new servo motors and new gearboxes.
I pulled it

Re: Gemini Motor Mounting Damage?
The first thing to check is that your Gemini settings are still correct. For example, HC mode should be Photo or All-Speeds, otherwise no guiding will happen. Then, check that you have the correct
