Hello:
when I print it seems like the horn on the pen lifter is always “on”. When I connect to the computer and test the pen up and down it responds as expected. When drawing the pen doesn’t seem drop down onto the paper.
Any thoughts?
Thanks,
Don2017-01-23 at 10:14 #12255DanKeymasterDoes it lift/lower at all while drawing?

I love your product although I am facing a few problem.
I am facing a similar problem.
The servo motor rotates constantly, it changes direction when I give a pen up or down command but it just does not stop moving.
I am using arduino uno with motor expansion shield without external power supply.
Is it a baud rate problem in the firmware or something else.
Do I need to comment out anything in the firmware?
The stepper motors are running fine by the way.

2017-04-22 at 10:30 #12917AnonymousInactiveBy “does not stop moving” I meant to say that the servo motor rotates continuously 360 degree as soon as I connect the arduino to the computer.
I am using this motor http://www.vegarobokit.com/index.php?route=product/product&product_id=192.
I dont think the motor has a problem, because when I connect it to the arduino and run the “sweep” code in their library it rotates 180 clockwise and anticlockwise as specified in the program. This is the program
I am unable to get the pen up and down as per the drawing.
2017-04-22 at 10:33 #12918DanKeymasterUnfortunately you’ve used a continuous servo, which is not the same thing as a 180 servo.

Thanks
2017-06-02 at 14:10 #13218AnonymousInactiveHaving the same issue (I think) as don, above. Did this get resolved for him? It seems the pen is drawing when it should be lifted. Thanks.
