This is what I’ve printed yesterday, it needs some smalle updates to fit the Arduino better
When this all fits well, I will share this @ ThingiFirse including the new servo pulley !
Hey Marten, that seems like a great modification. I have a question if you have a moment, since you designed the nerv boards. I have one servo (Rt arm omoplate), which when connected to the nervo board, gets hot and eventually burns when connected to the nervo board. The servo works just fine on a tester etc. I have seen in the tutorial, the suggestion to test the “+” and GND connection to see if there is a reading or not. “No reading” is preferred. Can you send me a photo of where the test should happen on the nervo board? I am having a tough time understanding where to get the multimeter reading?
Hmm, it sounds there is something else happen with your servo connection.
If there is a shortcut between the Arduino shield and the small PCB, the flat-cable will start getting hot !
Please double check if there is no connection between servo outputs 10 and 11.
If possible could you send me some pictures from your boards?
Thanks for trying to help me. I sent images via pvt email.
Please read this post from @juerg
Give it a try and see if this will solve your problem.
Which servo’s are you using in combination together, which gives you this “Jitter” problem ?
Do you have a oscilloscope ?
If yes, could you make and share some screenshots, when you measure these connections ?
