Have you had any luck with this? I was having a similar issue. I wasn’t sure if it was hardware,wiring or software. I ended up removing the signal resistor and using Arduino IDE. I was able to run example animations on all pixels just fine thereafter. Still no luck though in MRL.

Fantastic! This is turning out great!

Thank you both! I use an open source program called gimp to remove the background. Looks good on white, but it looks better on black.

It is also quite a useful tool for repairing damaged prints avoiding reprinting the entire part. Saves printer time and material!

Thank You ! I have all the eyes, head and neck servos running, but no others yet.
Trying to strike a balance between printing the parts and purchasing the servos.

You are so kind. Thank you very much! What a fantastic project!
