Machine: Shapeoko 3 xxl
Laser: jtech 14w pro
Software: Lightburn
New user here. Been happy with my CNC for years and finally decided to add a laser to it. Lightburn seems like great software but I have an issue that for the life of me I can not over come.
I have gone through the basic hardware and software setup that jtech supplies. All my settings are set up properly as far as I can see. My problem is this. No matter what I do, lightburn seems to scale up anything I tell it to do.
Example 1: Draw a 1 inch box. Lightburn ends up engraving a near 4.5 inch square.
Example 2: Set movement controls within lightburn to move at 0.5 inch. Click move X axis to the right one step. Laser ends up moving 2.25 inches (measured with laser test fire at both start and finish steps)
Is there some setting I am missing? Is my machine communicating in MM even though I have it set to inch? Please help. I can provide screen shots or any data to help.
