X axis moving from right to left in the X+ direction

[drhodes4601]

Hello again.
Just finished my first paid program for my antique Bridgeport Series 1 CNC retrofit. When I program an X+ move I am used to the table moving left to right. On the CNC graphing program, it moves correctly. When I run it on the Centroid it runs opposite, right to left. Is this just an easy parameter change to correct? Thanks!

CNC directions are defined by the direction the spindle "moves". X+ is the spindle moving to the right. On a machine where the spindle is stationary and the table moves, then X+ would be when the table moves to the left causing the spindle to appear to move to the right.

It sounds like your machine is wired correctly.

So when I program let's say G1 X2. F10., and I am starting at X0, it should cut 2 inches toward the right edge of the part. But instead it is cutting 2 inches towards the left side like a mirror image.

Here's a thread with more detail on the correct machine tool axis directions.

Post a report file so we can see how your mill is configured. A video of what it is doing vs. what you expect it to do would help.
