Thanks for the response. Have already checked the encoder seems spotless, cable ok as working with the my original pre SVM servo. Have been in contact with Tanya at Losmandy today... hopefully will

Could be the cable or the encoder has failed or is dirty.? Do you have a spare longer DEC cable as I tell people to keep on hand fo

Closing the loop on this for others. End result fixed most problems. Tasks completed to do that:- Cleaning and regreasing done and found the Dec/RA motor cogs (under the external covers) were heavy

Chip, John, Please take your personal squabbles off-line. It's been posted here before and I guess it's time to repeat it again ( /g/Losmandy_users/message/78913 ) : personal attacks

Pretty sure that the worm wheels are anodized after machining. Lapping will remove that hardened surface that results from that process. So not only is lapping unnecessary, it's to be strongly

Has anyone had SVM-HT servo motors that stalls? During an imaging session a couple of nights ago SGPro failed to platesolve, went out to check & found Gemini1 hand controller indicating a stall...

Hi Charles the nylon washer goes on top of gearbox flange (gearbox against mount) and stand-off post screws down on the stainless stud. ? Later models this was changed to a male/female stand-off (no

I have a G11 that was bought in 2008, it was upgraded about 10 years ago with new higher torque motors. I took it out in the field today to hoist my 100mm Lunt solar Ha scope for public outreach,

Thanks!

I would suggest that you leave PHD2's backlash compensation enabled.? It is a good way to judge the current residual backlash after any TVC compensation is applied.? Just make sure it never auto

Thanks all for the suggestions. I have completed all the cleaning and greasing plus readjusted the Dec worm gear. With hand testing it appears to have removed some of the backlash but the test will

If the motor gearbox is the culprit, you are in luck.? The gearbox and transfer gears present a constant amount of backlash and can be easily compensated for with TVC.? Just never let the

The worm/worm wheel interface (which is what your efforts have addressed) isn't the whole game: There is the motor gearbox, for example, along with any transfer gears between the gearbox output and

I think I'll be asking John Kmetz to send out some of the MP-50 lubricant he was mentioning. I did tear into the mount a bit last night and it's going to need a very thorough cleaning and regreasing.
