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 odd thing was Sky Safari on an iPad Pro (10.7¡±). Sky Safari was quite sluggish when connected. Lowering the readout rate to 1 or 2 per second (from the default of 4) improved things but it was surprising. Looks like the software is polling the mount in its main loop which is a bad idea for responsive user interfaces. Even at the lower rate there were periodic UI freezes as it polled the mount. Other than that everything went smoothly.
Unless you count the awful weather and cold I got since the mount arrived. I¡¯m now two weeks in and still haven¡¯t been able to get outside. Hopefully by the weekend!

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 2-mini w/HT-motors, new design OPWs, tucked-in motors, RAEXK etc. I also own and love my classic GM8G with HP worms that remains un-updated but will will get the tucked-in motors once there is room in the schedule at the shop. I have not worked with the? GM811G, I've watched all of the various prototypes being developed in Losmandy's shop but I don't know if they are being specified and shipped with the RAEXK installed or if it's simply being offered as an option.?
So with that said, if testing with an empty saddle I prefer to?leave the counterweight shaft on the mount because this prevents a worse imbalance than taking the counterweight shaft off. If you do remove the counterweight shaft the saddle side of the head will be much heavier and will rotate surprisingly quickly if a clutch is loose or loosened. If your GM811G has the RA extension kit installed it should not hit any other parts of the mount as long as the saddle is completely empty. Even so, with the counterweight shaft in place the imbalance will favor the CWD position and there will be no surprises if a clutch is let loose as the counterweight shaft will always rotate to CWD. Don't worry about the servomotors, even my very first generation Gemini 1 motors will handle this load no problems, the later high-torque motors will have no issue used this way either.?
Chip?
