Rotary Encoder behaves erraticaly

Post by Softfoot » Sun Nov 03, 2019 10:30 am

This is on my I3 Pro C with a GT2560 A+ board and LCD2004

It seems to need a variable number of rotation "clicks" to move the pointer on the menu - sometimes 3 or 4, sometime 1.

It also goes the wrong way to my way of thinking - I have to rotate it clockwise to move down and anticlockwise to move up.
Interestingly when on a number field it seems OK.

Any suggestions welcome,
Dave

Add two 10nF to 100nF capacitors between the three legs of the encoder.

TIP: tight all screws and wheels (except right side of Z axis) and re-align frame while assembly. And silence it.
