I’ve made a double size plotter using bits from an MakeBlock plotter contrololled by an Arduino + other stuff I’ve bought. I near to switching it on but I have a question which someone here might be able to answer (or send me to a forum which could answer it).
The x-axis has two belts. One connected direct to the motor and one connected via a rod. Should I add a second rod at the far end to keep the motion smooth/correct/something? I’m worried that since the rod is long it may twist causing the “other” belt to drag.
(I’ve just noticed that the rod seems bent. I stood on a chair to take the photo, I’d better check it really isn’t bent!)
