Hi, just hoping to draw on your experience.
I have just decided to start my design for a router. I want a working area of approx 1000mm x 1000mm, and will mainly be used for wood but I can see the need for some aluminium work.
I am going to base the final design of the router around components I can readily get, but I am having trouble deciding on the size of lead screws I need. I was initially thinking about 16m x 5mm pitch but I am unsure whether I should increase this to 20mm or 24mm.
Also I was thinking about placing the X axis lead screw central under the moving gantry and using a ball screw, but would two trapezoidal lead screws running either side of the gantry work as well and be of a similar cost?
I understand that having two ball screws on the X axis would mean two motors.
Any advice would be welcome.
