Allen I don’t believe tucked in motors are yet a feature of Titan, so I don’t think that error shows up on existing/current Titans. Thanks Brian Brian

Michael, I noticed you included a list of frequencies in PECPrep that included an entry Worm spur gear 31.9 sec. I have been trying to clean up the G11 T guiding. I bought PEMPro two days ago

Two last comments regarding power sources: We get dew around here (sometimes lots of it), so I avoid AC power adapters. Plus after cold soaking at -10C or lower I have seen them refuse to kickstart

Hi, Could anyone please tell me what the thread size of the Counterweight Shaft Safety Screw is please. Had an idea for adding some moderately adjustable imbalance. Thanks Pete

The motors (SAIA or Hurst) operate on 12V – the regulator is just there for the digital stuff. The Darlington transistor array (the 18 pin DIP at the top of the PCB) is connected directly to the 12V

Chip, If the grease gets to cold, it will slow down the stepper input into the gearbox. Easy to skip steps. The grease (used loosely) in the older Hurst gearboxes was more like a thin glue. Don

Hi all! Yup. It's just a 492 system. I replaced the plastic covers with the metal ones at the beginning of 2016 and was thinking, boy, I don't remember those gearboxes being that complicated, Mr.

Regarding the power source: The power input to the 492 goes directly to a 5V linear regulator, so any input voltage over about 7V is just wasting power — it won’t benefit the motors. -Les

Dooh! I knew that! But this just makes my comments even more relevant as the integrated stepper/gearbox is even better sealed than the servomotor gearboxes. Additionally with the higher gear

Chip, Bob is running the 492 drive with the stepper motors. They have a 150:1 gearbox. Don

Bob, If your mount is only two years old the gearbox lube is probably fine because the gears and lube are all sealed up in a nice closed clean environment that operates at a very low load and

Thanks to everyone for your answers. I actually just set the mount on the table and ran it without the CW shaft and everything seemed fine. Software seemed to connect and control properly. The only

Hi Linda, My old G11 was a 15 year old mount that had a new Gemini 2-mini w/HT-motors and HP worms on both axes. I had Scott rebuild this old G11 as a fully optioned current spec. G11G - Gemini

Linda, As the shaft weighs over 2 kg, I suggest you remove it also. There should be no problem in running Gemini without a load. David

You can set the Gemini Tracking rate to Terrestrial mode (not sidereal, lunar, solar,...etc). This stops the RA worm and tells Gemini not to expect any ticks from the optical encoders. As for the

I’m working on getting my GM811 set up with software and I had a question about what was the appropriate way to run the mount without any OTA. Should I remove the counterweight shaft or leave the

Hi Don! Ohhh. Unless I saw the grease I would have forgotten about it. Didn't even think about the gears. I hope I can get to this this week. Thanks! Bob

Bob, With the 492 system, don't forget about the grease in the motor gearbox. That grease can cause a slowdown much more than the grease on the worm. Don

Hi Bob, If possible you really want to use solvent to wash out the old grease and contaminants, blow out the bearings with plenty of compressed air BUT be ready for a lot of black lube to come out

Greg, I have SharpCap 3.1 polar alignment works very well, actually excellent. I just preferred the PoleMaster's camera sensitivity and software guidance. The PoleMaster's software, to me anyway,
