Arduino mega 2560

Hi. I don't know alot about micro controller so if somebody can help me. Is it possible to upload this firmware or settings from this controller control system based on STM32 processor, paired with the ARM Coretex M3, running a dominant frequency of 72MHz, to a GT2560 controller?

I like to upgrade my printer which is almost the same except controller and I have GT2560 controler this one have some self developed controler. control system based on STM32 processor, paired with the ARM Coretex M3, running a dominant frequency of 72MHz, http://www.ebay.com/itm/272109501355?_trksid=p2060353.m1431.l2649&ssPageName=STRK%3AMEBIDX%3AIT

No, the 2560 is 8 bit and the STM32 is 32 bit.
