Pen is moving to far
Hi guys,

i'm pretty new to the sphere-o-bot but it's already printed an runing, more or less.
I just have one problem with the pen motor. It seems to move way to far, as it hit the edge of the frame while prinint the small eggmaze pattern as test.
How can i solve this issue?

Any help or hint would be great.

You can adjust the height of the servo arm via the SETUP conf:

Thanks for your answer. It's not about the height of the pen but the movement of the stepper motor for the pen. The pen holder moves to far until it hits the bot's frame.

Oh, I see. The cause of the problem could be the size of the drawing. You can use the first template of this page as a reference:

This is a blank template that will fit on most eggs: https://www.jjrobots.com/wp-content/uplo...MPLATE.png

maybe the servo arm is placed to high and you need to screw it of and take it of and place it a little bit turned down?
