Hi all.
I'm building a CNC wood router machine , but i'm a little stuck with the mechanical things . I am trying to get the acme threaded(or square) lead screw and the stepper motors , but i dont know the specifications, which should i get first?? how to choose it's specification???
what should the speed of motion on each axis Be??
My machine is a 3 axis wood router , i'll be drilling MDF wood.
Y-axis : 4 feet long ,25 lbs horizantal movement
X-axis : 2.3 feet ,14 lbs horizantal
Z-axis : .6 feet ,11 lbs vertical

Check out other people's project logs to see what they have used -- it's the best way to learn. Also, you might check out the plans Solodex and I have posted recently. They are very similar in size to the machine you are building, and have a complete parts list for the ACME rod and other components needed. You can find them both on cnczone and on my website.

Best regards,
