I’ve embarked on making a 4-motor machine on a larger scale – say 5m x 5m. At first I discounted makelangelo because I thought it only did 2 motors but came back to it after I found it does 4. In the mean time I had started on the math and got a bit overwhelmed with the pathing. I suspect I made the problem more complicated than it needed to be, but I wanted to handle acceleration and deceleration of the stepper motors within their limits while maintaining accuracy and as close to constant speed of the drawing mechanism as possible. From the comments in this thread it appears that there may have been issues like that at first with the zarplotter. Can anyone comment on this issue or point me to the code that does the conversion from cartesian coordinates to motor steps? How is acceleration and deceleration handled?
