Step 18: Stabilize Rotary Encoders (optional)
Parts used:
* JB-Weld
Description:
* If you have removed the detention of the encoders, you may have noticed, that it is quite difficult to close them properly again so that there is no unwanted wobble/movement when applying off-axial force to them.
* Even with calipers and some muscle, the encoders would not reach the stability of an unopened (still detented) encoder. Even worse, over time the clamps loosen a little bit, making things worse.
* Therefore I recommend to just apply four tiny blobs of JB-Weld on where the brackets meet the upper encoder case. It stabilized things a lot for me (photo 1).
* Make sure you don´t get any JB-Weld on the encoder screw threads, we will need those later on :-)
Note:
Should you ever need to replace an encoder, use a wire cutter to cut it just above the PCB and then use a vaccuum pump from the backside and your soldering iron from the front side to suck out the short pin remainders.
