Thank you both. Great points and info. Chip, it's great to hear you're seeing the same results at both ends of the voltage range. That's a completely valid point about cheap & easy to get power supplies that are under 18V. Shoot, that 90deg DIN connector cost more than the power supplies you mentioned.
My mount has the early high torque motors and was recently cleaned & re-lubed.
I had it under the stars for my first time tonight. I have some kinks to work out with NINA & slews, but otherwise everything seems to be working well.
Thanks for the help!

I never tested or timed it but AFAIK Gemini slew speed is set by the Gemini under the "speed" settings and the encoders which look at motor speed and counts for position just let the Gemini know to send more or less juice to the motors to regulate speed. I think for some folks the additional voltage helped overcome mechanical stiction/friction and startup loads issues due to poor adjustment or balance.??
There have been a few different Losmandy servo motors available. The "high torque" motors are marked as such with a "HT" marking and/or have additional machined cooling fins on the servo motor body. The Maxon servo motors had full length body cooling fins and the original Gemini 1 standard torque servos have smooth bodies and no fins at all.? ? ?
