Im hoping someone can shed some light on this. I make coasters on a 600mm square sheet of plywood. 36 coasters 95mm round. I frame this everytime before i start engraving and cutting them out. Havent had a problem with the thousands ive done before i upgraded to 1.7 but now one side chops off an edge of the coasters. Its almost as if the plywood has moved before i start the job. I know thats not the case because i tape the wood down everytime before i start. I dont understand how it can frame the job with no issues yet when it comes to cutting out it suddenly cuts into the coasters.
Boy. I dont see anything that stands out and the preview looks good. Couple of things i would try
Do the frame and get everything set up to cut.
Then use cut selected graphics only and do the right column only and see what happens.
Then do the same thing and and select the left two columns and see what happens.
Switch the middle and right column position and see what happens
Wonder if it could be a mechanical problem.
Couple of other things. Is the rotary disabled. Are you set for Absolute Position
Turn on Check Bounds When Framing and see if it tells you anything
Switch to Current Position and manually move the laser head to the correct position then frame and cut and see what happens.
Im running version 1.4 of lightburn. I tried this on my machine and the circles cut fine. I’m thinking this is a bug in Lightburn. Or maybe the fact you did the design in an earlier version of Lightburn
Here’s something to try. Open each of your cuts/layers and click on Reset to Default. Then change the Power and Speed back to the original setting and resave your file. Then try it again.
