Hello friends, I had some Amazon dollars burning a hole in my pocket. So rather than designing and/or building a 3DP true Diy I purchased a Hictop Prusa clone. Total cost about $40 with two spools of filament, micro drills, and spatula. I finished the build last night and Im trying to figure out how to update the firmware. The card is a custom arduino mega using marlin, but I don't know anything about the realm 3DP hardware/software yet. I'm hoping someone can point me in the right direction. The printer firmware has to be updated to allow mesh leveling from the inductance sensor because I bought that piece separately. So far I've downloaded Cura, have a copy of the firmware I want to install, but haven't installed any drivers or connected to the PC yet. The firmware update file they provide is a Marlin cpp.hex file. I don't know where that goes. I just want to print already. Thanks for any suggestions. Joe S.
