Machine: FullSpectrum conversion
Problem/ Question: Hello
We are using Lightburn
We are setting up our machine for the first time and we are having issues the material thickness setup.
We are using a cohesion3d variant of the smoothie board with our z home set to max and we have a working limit switch at our max position.
Currently, after homing we have the table z value set at 0mm which is our focus distance away from the lens. (everything with our homing seems to be working correctly. After homing our z it goes to z0 and when we press “Get Position” on the move tab it says z:0)
Now when we run a job with a material thickness of 3mm, I would expect the table to move down 3mm to compensate for the height of the material, but instead, it moves up 3mm so now I am out of focus and too close to the laser. The material thickness box does not allow for a negative number.
The z offset does allow for negative numbers but it returns to z zero after the cut so if we had a tall project on the table it would collide with the head.
Does anyone have any ideas on what we are doing wrong?
Our goal is to have the bed automatically go to the right height for whatever thickness material we are using based on our library.
I posted this in the light burn forum and they said it would be better suited for the cohesion3d forum.
