Yesterday I went and had another read through a RuiDa Manual ( despite my controller not exactly being one ) and one particular setting sparked my interest - that being Speed factor % (0 to 200 )
- as it mentioned the speed when doing arcs of various sizes.
Low and behold reducing it from like 80 down to 30 would now have the Laser do nice Rounded Corners without the wobbly overshoot when transferring from a Y-Axis Motion into an X-Axis one =)
