Thanks for your response.
I understand the Ultimaker has a complicated x and y-axis movement. I wanted a mechanical/electrical explanation of how this process works. In the quote I posted; the article tried to explain it but it still isn't clear. I don't own any Ultimaker to make this observation myself. I hope this is clear.
I find images clearer than words. Do you have an Ultimaker? What do you want to know anyway? Mechanical details? Or electronics details? Or firmware details? All the parts have to work together.
Mechanically you can just see how it works if you have one.
Electrically there is a stepper motor and that is connected by 4 wires to the stepper driver. I could go on for hours about stepper drivers and steppers.
In the firmware is complex logic to move all 4 axes linearly. I could go on for hours on that also.
Maybe it's best to be more specific about what you want to know.
