Hey Fellow Creekers,
I will take possession of my 4'x4' cnc next week. It is definitely older. It has Applied motion 4034-324D stepper motors. 2 each on the X, one on the Y and Z. For sitting unused for awhile its not in horrible shape. The frame is outstanding, it is 3" box steel posts and 2 rows of horizontals with at least 4" mounting plate for a box aluminum upon which rests the guide tracks and the ball screws. Along with it come a pair of Porter Cable 75812 routers. I have several questions, pictures will follow once its in the garage....
Oh yea, the gantry is one piece of that box aluminum. i tried to move the router and it wouldn't budge in any direction.
1. Do I keep the steppers or replace them with larger ones?
2. Any good tips on extending the life of the routers? Some sort of a cooling jacket to keep the heat down? Or just upgrade to a liquid cooled spindle?
3. I did notice that the X steppers were wired together, not sure that correct
4. Budget, at least $1k or more available for parts replacement, the price of the machine is very good....
5. Who is going to stop by and help me move those 28 4x8 1 1/8" sheets of decking at 125lbs each.......
Bryan
PS the deck is a big piece or two of slotted aluminum, pretty beefy by itself.....
