I have an older 8-bit chip analogue Bartech unit with M-One motor. Occasionally I will be on a rest in-between shot and even during some shots, the motor will freak out and begin to sound like it's trying to move. It will not move but it will go on the fritz and sometimes twitch. All this happens also when my 1st AC isn't even touching the hand unit. That's what's so odd.

I've had this happen to me before and a fresh battery for the receiver and motor seems to fix the problem.

I have this system.  I bought it new, and it had the problem day one.   I contacted Jim Bartell and Don Wetzel of Loon Works whom makes the M-One Motor.   



Immediately Don Wetzel knew the problem.  The potentiometer inside the motor is the ONLY part that is wearing it self out.  The only part in the entire assembly which Don states no matter how expensive or well manufactured the individual fomponent is, which he states he is using the expensive best made part...


it will wear out eventually, and it doesn't stop working, it slowly starts to intermittently fail.   



The ONLY way to remedy this annoying wiggle squiggle shaking of the motor ... this random minute but loud and noticeable vibration of the motor back and fourth attempting to lock onto a stepper position is to replace the potentiometer. 



So... As long as the unit is beat up on the outside and looks like you've cared for it... for the most part, don't quote me... but if it is a fairly recent purchase and you pay for the shipping to MONTANA where LOON WORKS and Don Wetzel are located,,,   he might replace it for free..

He did for me.




Guarenteed to solve your problem! :)


I just wish I had contacted Don long long ago and saved myself the issues on set, the AC's not sure of the devices reliability or performance.


Let me know if you have any other problems.
