My daughter gave me and my grand daughters a Watercolorbot for Christmas. How cool! Gravity and other forces cause the plastic cable guide to rub and snag across the X axis string as the carriage moves back and forth across the X axis. I have tried several approaches to adjust the plastic cable guide so it will consistently rides above and clear the X axis string. I have removed it and turned it around. I have tried to reposition it at an angle. Nothing I have tried has been able to defy gravity. I the snagging of the X axis string appears to be causing the X axis motor to become confused. Any adjustment ideas? There is probably a simple solution that I just have not thought of.
