So of course being made out of wood and within a month it will not be very accurate nor will it be good at cutting certain materials however, I plan to greatly improve my design and work towards making it more stable and rigid.
With the code I developed, I was able to make my name in a piece of styrofoam, in styrofoam, the cnc is most effective, however in wood due to the lack of stability and rigidness, it is not quite as effective which is why you see deviations in the path of the lines.
Instead of relying of plywood I may implement 2 by 4 or someother thicker wood and I implement stronger steppers.
However what I am going to implement is a actually cnc spindle which is around +$205, even though the spindle has a lower max rpm than the dremel the spindle has something the dremel doesn't and that is torque, about 500mn.m which maybe enough to cut through wood effectively.
