Makelangelo 5 Servo Location

[Anonymous]

Hello Makelangelo world.

I am so close to finishing my Makelangelo 5 bot for my class. I am having trouble with my display (different model) to what Dan uses, and I dont know exactly where to plug the servo to lift the pen.

If anyone can help with this let me know..

cheers

You’ll want the bottom right corner of EXP3 on a RUMBA board. note that the the ground and power wires have to be swapped. Putting power backward through a servo is bad news.

No love,

I have tried 3 different servos thinking maybe it was the servo that was busted.. 1 was clean out of the packet..

How do i test it other then pressing pen up and down??

cheers

My servo has the Jitters.. DOnt know why lol

It works and moves in and out.. but it jitters for a bit..

cheers

could be poor quality servo, could have been fried by putting current through it the wrong way, could be noise from a bad RUMBA board, could be low power? That last one is unlikely.
