Most of you recall my custom GP38 project. It was running great until yesterday.
At slow speeds (1-5 speed steps) it would lurch and shutter. There was some improvement from 5-10 steps but still a noticeable movement that was not smooth. It did not smooth out until I increased the throttle to more than 10 speed steps.
I thought it was something electrical with the board inside. Upon inspection after opening a number board light wire and worked its way over the motor flywheel just enough to effect slow speeds. At 10+ speed steps, the flywheel was moving fast enough to break free of the wire.
Check out the damage the flywheel did to the blue shrink wrap. Glad I caught this. I replaced the shrink wrap, re-routed the wire and am back in business.
