  • when changing the size to the new 430mm 900mm the absolute coordinates are no longer accurate. If I move to coordinates 80, 80 fire the laser at 10% power to produce then home, and repeat back to coordinates 80,80 fire the laser I should only see one dot but see 2. If this is repeated multiple times I get multiple dots. Not sure whos issue this is but plan on emailing lightburn as well. 

  • After setting the working Dimensions for the D1 Pro with extensions, I have to hit Home 2 times, sometimes more, to get it to the home position. Why is that?

  • I have just installed lightburn and the origin is in the back left corner of the machine (like in the picture above); I cannot get it to move to the front left corner of the machine and the y axis is going in the wrong direction and so are the move buttons. I installed the extension kit, and also the homing is not working correctly; if the laser is in the front half, pressing the home button will send the laser to approx. middle of the distance; then if I move the head manually using the buttons, and press the home again, it will go to home. Any suggestions are much appreciated.

  • D, did you use the Xtool program(XCS) to update the firmware for the extension kit?
