Luis,



I'm not in front of my mount right now, but I think the default slew and GOTO speeds are around 800. I had to lower this to 600 to avoid occasional stalls. I have a C9.25 and 66mm guide scope, so my weight is lower than yours, but otherwise with a similar setup.



I know you said your battery power was OK, but low voltage can also cause stalls. I had that happen to me when I added another dew heater strip to a shared power supply, and started getting stalls.



Another reason for stalls is that one of the worms is too close to its gear, so it might need to be loosened up slightly.



Good luck,

-Joe

Losmandy specifications said that the instrument weight capacity 60 of my mount should be 60 lbs. Is it this amount overstimated? Other reasons for this uncontrolled slewing? Thanks.

What is the input voltage from your power source? If its only 12 volts your may want to use higher voltage. ----- Original Message -----

I own a Losmandy G11/Gemini v4. The weight of my instruments is about 45 lbs (OTA Celestron11, Orion 80 short tube with rings and dovetail, SBIG402 ccd,...). The motor stalled in GO-TO function frequently (3-4 times by night). The battery power and the telescope balance are OK. Losmandy specifications said that the instrument weight capacity 60 of my mount should be 60 lbs. Is it this amount overstimated? Other reasons for this uncontrolled slewing? Thanks.
