Thanks Graham- I tried the newest beta firmwares today. They are pretty buggy on my end: Motor selection doesn't work & Motors still won't calibrate to name a few... I have a big job coming up next week so I will certainly revert. (Last time I used a beta on set was in February when a DP really wanted to use the MIMIC but every time we switched it on, MPro spun to a new front position hitting the ring. Issue resolved now but what an embarrassing MIMIC debut!) The other MPro & MIMIC Pro are on the latest Beta firmwares. Yes! The Freefly motor cables and RedRock Torque motor worked on 7/16/2017 for one brief test but haven't worked in 3 tests since. I tried updating firmwares on Pro & Mimic, rebooting & reinstalling firmwares then the current betas. No dice. Thanks for your time, Deniz!
