I am using a G540 and Mach3. Using the xml file from the Geckodrive website. I have two new Automation direct steppers to run the gantry.
I slaved the "A" axis to the "X" axis and reversed direction on the "A". I began jogging and it moved correctly. I attempted to jog in the other direction and found that the "A" side motor would always jog in the same direction regardless of the arrow I pressed.
So far I have:
Reversed and "Unreversed" the "A"---same problem
Slaved and unslaved the "A"---same problem.
Swapped motors and cables--same problem.
Closely checked pinout settings. They match the Geckodrive sheet.
Changed the pinouts on the "A" to the "Y" axis settings then attempted to jog using the "Y" axis arrow key. It still always jogs in the same direction regardless of the arrow key I press.
Regardless of all the tests I have made it seems that any motor plugged into the "A" axis on the G540 always rotates in the same direction when jogged.
Any hints or ideas would be greatly appeciated.
