G'day all.

I wonder if anyone could help me.
I have set up my eggbot and on first inspection all seems great. However when I start a plot, once the pen arm moves past 5 degrees from the vertical centre position it runs to the end of its reach and is unable to correct and carries out the plot at the far left hand side or right hand side of the egg.
I also notice it will not return to its original centre after finishing. (this option has been checked in inkscape).
Thanks

It sounds like the motor current needs to be adjusted. That is, it sounds like the current is presently too weak and the pen arm motor cannot hold its position while supporting even a small fraction of the pen arm's weight. See

for pointers.
