Piccolo issue

[Josephhines]

My piccolo is fully assembled to the specs [with ardunio uno]. However, when I run the tether usb sketch the cnc slowly moves around [mostly jerking motions in the Z axis] but never moves on to the test circles when i press the test button.

When i try to upload another drawing via controllo there is no discernable change. any thoughts?

any update as to when a help forum will be established? [the link is dead on the site]

Hi Joseph,

This potentially sounds like a issue caused by electrical noise from the servo's. Could you try adding nice big capacitor between 5V and GND on your Arduino?

Hey Greg,

I currently have a 330uF 25v capacitor in place. still struggling with the same issues. Any other thoughts?
