Im working with cnc router 4050x2050( chinesse ofcourse) and a problem came up. 4050 is Y axis, and its my biggest problem. Im cutting acrylic most of the time,so i prefer perfect cut(smooth edges) , but now they are not smooth enough. Im sensing machine lacks of rigidity on Y axis,X axis cuts perfecto. How can i fix this. Y axis on runs liner bearings and two AC Servo Motors. What can be done? By the way Z can go up tu 400mm so its a tall machine, that makes it more difficult for Y axis, i understand, but still i more rigidity would help. Did anyone have\had this problem. Or maybe there is a Beautiful Mind umongst us? Cheers lads
