Very interesting what worked on your car! Completely the opposite of mine. Which Torin machine is your car? The one I just couldn't get to do a roped alignment is their mini gearless version with two flat normal brakes (one on each end of machine) model TMGL3-4535. This is with the HPV900.
I have another job with all of the normal size Torin gearless machines that have the disk brakes, one normal and one the ebrake, model TGL2A machines. These cars have F5 drives but KEB is similar they also have a unroped open loop alignment method and roped stationary alignment method. On these cars I've had no problem at all doing a stationary alignment with an empty unbalanced car. I've never tried the other way on these.
