Hi All, I have my new router build done and am setting up Mach3. My steppers are turning using the G540 XML file. Every thing runs fine, I just need to figure my travel setting out.
Hopefully someone can help out.
specs:
Steppers are, Keling KL23H284-35-4B 387 oz-in
Controller is Geko G540
A and Y axis screw are McMasterCarr 5 Start ACME 2 turns for 1"
Z axis is THK KR33 ballscrew/actuator with 10mm per one turn.
My config is setup as inches.
-
5 start screws should be 4000 steps/inch.
Z axis should be 5080 steps/inch.
-
200 steps per rev for steppers, 10 micro stepping on the Geckos so thats 2000 steps per motor rev, 2 turns to move one inch so that is 4,000 steps per inch for A and X (although maybe you are meaning X and Y ? )
Z axis is same for motor and drive so that is 2000, the ballscrew is 25.4/10=2.54 turns per inch so 2000 x 2.54 = 5080 steps per inch for Z.

Edit
Looks like I was beat to it LOL

Thanks ger21. Is there a formula to arrive at those figures for future reference?
Also I'm using your touchscreen screen, very nice!

yes, thanks, I meant Y instead of A, thanks for the formula
