need helping

hi! my name is emrah in turkey. this product is very interesting. ı want to do this product but ı will do all in one (laser,router,3d printer).

Where am I changing the firmware(marlin) to use the laser or router( I looked site but I could not find). Is there a large printer also makes this system. for example 150cmx70cmx70 cm. I looked 4 head on site.

thank you so much…

The only change in firmware you need to make is for the Leo laser, if you use the Jtech no fimware change is needed it just costs more money. Printing and milling use the same firmware.
