Toolpath Reveresed
« on: July 17, 2017, 09:28:45 PM »
I recently completed installing a PMDX-126 breakout board, ethernet smoothstepper and a PMDX-107 sindle control board.  Got everything configured and running.  A couple of days ago I ran my first test job.  All went well except the toolpath direction is reversed.  I checked my gcode and confirmed that the CAM software (CamBam) generated the correct G3 code for climb milling.  Is this a Mach3 configuration issue or a smoothstepper setting?  Before blindly changing my Mach3 configuration settings I'd like to get some input on why this is happening and what settings I need to change.  Running Mach3 version .062.  I've also attached my gcode file.  Let me know if you need my XML file.  I'd attach it now but it's on my shop computer.

Thanks

One or more axis on your machine are backwards.

Thanks for your response.  I changed the X and Y motor outputs Dir Low Active and Step Low Active from a green check mark to a red X and no difference in cutting direction.  Or should I reverse the Step and Dir pin numbers?  Or is there another setting I need to change?

Just change the DIR pin, and only do one axis at a time.
