is it possible to edit the K40 chinese laser cutter's firmware to have longer traver X-Y?

[Prophet_id]

I am planning to but cheap K40 Chinese laser cutter and expand the X-Y table to get larger working area.

My question is: how to edit the firmware on the control board to take larger X-Y table?

Thanks,
Dan

Assuming your plan includes converting to opensource controller and firmware, that's just a matter of setting the size in the relevant configuration file.

However, I would say you'd be much better off just building your own machine from scratch. You can get better optics, tube and PSU than you'll find in a K40.
