Trying to fix my twitching servo when moving axis, following advice from this forum. So far I have tried adding a ferrite bead, and feeding 5V directly to the servo, bypassing the Arduino. No effect.
Don’t have my laptop so will have to wait until tomorrow to try messing with the firmware. Has anyone encountered this? What worked for you?

It sounds like an inherited problem with the servo itself, not the firmware or controller. It’s pretty common in nitro rc cars and numerous problems can cause them, not enough lubrication in the inner gears of the servo is one. I had the same problem on my rc car, lubrication did help a bit but not much, is it an old servo? Try googling “rc car servo twitch” or similar, but it will probably tell you to buy a new one.
Thanks, I should have updated but in the end it was a software problem. Disabling the servo during moves solved the issue.
