Hello,
I am using the OMGLaser with EZCAD firmware.
Been using the 150x150 lens with no problem. I made a border of 150mm length and 50mm height with the canvas of 150x150mm. So when I press frame in lightburn I get the exact measurements of the 150mm and 50mm border but when I changed the lens to 200x200 and changing the device lens to the 200x200 lens thus getting a 200x200 canvass the border I made with the 150mm by 50mm is not the same as the actual measurements. What should I do so that when I use a different lens aside from the 150x150 I would still get the exact measurements. I also tried using a 300x300 lens but got the same problem.
Have you tried aligning the red light pointer for your other two lenses ?
If not, give it a go. Here’s a video explaining the process.
Each lens will have it’s own correction information. Create a new device, with a name that references the lens length and import your mark7cfg file. Then you have to correct for the lens.
There’s a bunch of videos on lens correction, using Lightburn or with EZCad2’s Corfile2 software.
