Thank you for your reply... no it is still fitted to TM. IMO the LED flickers normally. In the video I was trying to set calibration but the speed fluctuates due to the behaviour of the motor... in the other video listen to the motor trying to increase speed... [videos]Is the motor on the T.M. or on a separate application?
If it is using the pulse wheel on the motor, this could be part of the problem.
No uneven mechanical load for sure. I’m pretty confident it’s the controller board... but don’t know where to start from, capacitors? PWM controller?not a bad commutator section.
Not sure what the problem is but I suspect there is an uneven mechanical load; something wrong with the belt in a certain spot that makes it have to try very hard in the same place every time. try tuning it by hand and see if there is spot that is hard to turn.
