How to handle the repositioning issue on TTS 20 Pro

Try this. Ensure auto home on startup is disabled. Place the laser head somewhere in the middle of the bed. Turn off and restart the laser. Restart Lightburn. Now go to the move panel and click Get Position. It should report X=0, Y=0, Now use the right arrow, then up arrow, then left, then down. Does the laser move in the correct direction with every arrow? Report your results.

  Thanks for the response. Left and right move in the correct directions. Forward and back is not correct. Up button goes down (towards the front), down button goes up (towards the back)

  The Y portion of GRBL parameter $3 needs to be toggled. You have to be connected to your laser and I am 1000 miles from my machine, so I cannot provide a screen shot of where to change it.

  In the Edit menu go to Machine settings. Click Read. Click on Outputs Setup at the bottom. Click Yes to allow changes. Scroll to Y direction pin invert and toggle that setting. Click write and test movement again. If it moves correctly, try homing. If it still homes to wrong corner return to Machine settings and toggle Y Homing direction invert.

  That setting was turned on, so I just turned it off and now it is moving and homing beautifully, now to learn how to use it. Thank you so much!
