I have worked as a CNC programer for over 20 years, and now I am working as a Engineer. Only after I stopped using CNC machines did I build my own CNC machine to play with. Leehound Where do...

where is the 2nd annual CNC workshop? and what date is it on?

I have made some Xmas ornaments the last 2 years. I had a great time putting the router together and getting it to work. I am using AutoCAD and a old ver. of E-Z mill.

I am also in Athens TN.
I have build my own CNC Router in my garage. Go to the "Photo Gallery" under "DW61" to see photo's. I looked at the K2CNC machine before I build my machine.

mine can cut at 75 IPM.

The HAAS manual has a G107 (cylindrical mapping ). Which means you program the shape flat and use G107 to wrap it around the round part in the 4th axis.

I have bearing block at both ends, made out of MDF on my machine (it takes a milling machine to make a milling machine). I have roller skate bearing in the blocks with nuts holding them in place. The...

I check on replacing my stepper motors with bigger ones,($200+ for each motor- times 3 motors-). That is when I found the timing gears and timing pulleys. Parts order off the net for 3 assembles $75....

Let me just think out loud:

So if I replace my 1/4-20 lead screw with a 4 tpi acme screw I should be able to go 5 times faster as I am going now with the motors turning the same speed. With less...

I have 1/4-20 all thread. That come to .000125 per step. I was going to start cheap, and later if I need to upgrade to something else.

I got my machine back together last night. I ran a program at 30 ipm with no lost steps, Before I could not run at 12 ipm without losing steps with the same program.
Seeing my machine cut at 30 ipm...

It will take me another day to get my machine put back together so that I can test it. I will post then.
I think I have more useable torque with 40 tooth timing gear on the stepper motor and 10...

right now I only have the "X" axis this way. I am changing the "Y" and "Z" also.
Before I change to the timing belts, My machine would not go over 10 ipm with out losing steps.
Now with the...

oops
I got that backwards, 40 tooth timing gear on the stepper motor. 10 tooth timing gear on the ball screw.
works better than the direct drive did on my machine.

"When in trouble,...

What I am trying is a gearing up. I got a 10 tooth timing gear on the stepping motor, and a 40 tooth timing gear on the ball screw.
So the motor turns at 150 rpm and the ball screw turns at 600 rpm....
