Hi, This is first time to discuss on forum. It's so exciting.
I sent several emails to Basecam's supporters and got solutions many times.
But I have more issues. I believe that many people's discussions will solve the problems.

Befor the problem, describing status;
I make gimbal with Simple BGC 32 bit - encoder enable and only using at Roll axis.
To prevent excessive rotation, apply stopper each 90 degree side as hardware.

Using this board I've had too many troubles.
I know lots of that are my fault and mistake.
Now I have a I2C error issue.

I set the board, and did IMU calibration.
IMU calibration done, I checked.

But when Motor power on, I2C error occurs and increases.
Gimbal looks like trying to stabilize but some trouble like zig..? tic..? symptom.

First, I thoght it is IMU or it's cable problem. but I changed IMU and cable more than 4times, issues are occur same.
Second I thoght it is motor problem. but Why I2C errors count up?
And I found green LED blinks slowly and constantly even gimbal have no motion.
In manual, blink slowly means that calibration is going on.
I calibrated and double check.

This gimbal, I used it well with same board and motor, a month ago.
It worked well, no problem, Just left in cargo a month.

This problem has been constantly and intermittently and has been solved by changing the board or IMU each time.
Now I want to know what is fundamental trouble.

Anybody else know about this issue? or similar experience?
