Hey guys,
I have heard of some problems with the roll being off on some Zenmuse gimbals. If you have a problem where the Roll is always a few degrees off (Even after a warm up), Then this may be a fix for you. This fix came from one of our customers CAZ. It worked perfect for him so I thought I would share it just in case it can help someone else. Credit goes to CAZ for sharing this fix with us. Thanks a lot bud, I imagine it will help someone else.
I take NO RESPONSIBILITY for people attempting this fix. Please only attempt at YOUR OWN RISK.

"The roll axis gimbal is secured to the servo shaft with three screws, one regular and two set-screws. Photo(1)
Then, there is groove milled in to the extruded aluminum casing around the shaft, (Photo2) and, as luck would have it, DJI milled a hole in the servo shaft within that groove. Photo(3)
Clearly, the design/engineering is such that they anticipated needing to make such adjustments/calibrations.
So.... With screwdriver and allen-wrench in hand, I set the Hex on a perfectly leveled table. Then:
1. Powered up the TX and connected the batteries on the Hex
2. Waited for the Z15 to completely stabilize
3. Powered on the Sony Nex5 and FPV downlink with the display set to the crosshairs
4. Loosened all three screws
5. Inserted the allen-wrench through the slot and into the hole in the shaft
6. Applied torque to the camera mount and gimbal in opposition to the roll axis servo shaft while using the allen-wrench to hold it stable
7. Repeated step 6 until the camera cross-hairs registered true level and remained there without any creep or drift.
8. Tightened all three screws and confirmed level with camera cross-hairs and bubble level on top of camera mount.
9. Powered down entire system and re-powered several times to confirm calibration
All is good.
Gimbal is smooth, steady, and level.
