@fcwilt what about for someone that didnt know what they were doing that has to start fresh on a duet2wifi that i cannot figure out how to change firmware on becuase all i get is weird errors and now i cant even access the DWC casuse the ip address keeps changing?what would you tell a person like that to do?

hello.i apologize for anything that may sound stupid here but i am pretty new to firmware on the duet2wifi board.i recently got a rostock max v2 and decided to try to upgrade the hotend and control board.at first i was able to somehow get the printer updated to 3.2.2 of the reprap firmware.for some reason all i get is errors telling me things like Error: M997: In-application programming binary "Duet2_SDiap32_WiFiEth.bin" not found or duet2combined firmware not found.at this point i have a ton of money(over 900$) invested in this printer and i just want to see it successfully print at least 1 benchy by xmas. i have no clue why i am having so many issues other then the fact that i am very ignorant to this entire reprap firmware on a seemecnc machine.i have some slight knowledge of how to compile firmware on something like an ender 3 v2.i have been trying to get it going since march 14th 2021 and spent countless hours of wasted time trying to get somewhere but it seems to be 1 step forward and 2 steps back.sometimes i do something to make the network disconnect or the paneldue to stop telling me the network address so then i cant figure out what IP address to connect to the DWC.its just so frustrating. i hate to beg but i am not too proud to do so anymore.please can someone hold my hand like a 2 year old and walk me through the entire process and help me to get the proper files and configs and firmwares and everything needed to make my xmas wish come true this year and produce my first benchy from the rostock max v2?merry xmas to all and god bless.TIA
