Quote:So at the end of the day, something like an Ovision worm with PEC applied would only have say 2" p-p of PE... but the gearbox PE is still there. I believe this is why some G11 users replace the regular motor with a Maxon.
Quote:The TDM will also fix PE problems regardless of whether you are east- or west-heavy. This would make balance less problematic / critical.
Quote: Finally, I installed a small stainless steel shim between the M2.5 mounting screws and the screw slot on the new high torque motors. The other option is to drill and tap the gearboxes to accommodate 4-40 screws like those used with the stock Losmandy gearboxes. I chose the shims instead to avoid opening up the gearboxes to drill and tap.
Quote:As the new screws are slightly undersized, put a wrap or two of tape around them where they fit through the motor housing.The motor is in a very slightly different position, so only tighten the gearbox cover screws after you have fitted the motor.
Quote:2) the motor gearbox contributes significant PE; we know on the CGEM it can be as high as 25" p-p (can be more than the worm fundamental) but for good-quality Japanese gearboxes the gearbox PE would be around 5" p-p
