Config:

While compiling with //#define PRUSA_MMU2_S_MODE following compilation error occurs. It was not there earlier.

Marlin\src\feature\mmu2\mmu2.cpp:346:16: error: 'mmu2s_triggered' was not declared in this scope

in mmu2.cpp

find

        if (ENABLED(PRUSA_MMU2_S_MODE) && last_cmd == MMU_CMD_C0) {
          if (!mmu2s_triggered) {
            can_reset = false;
            // MMU ok received but filament sensor not triggered, retrying...
            DEBUG_ECHOLNPGM("MMU => 'ok' (filament not present in gears)");
            DEBUG_ECHOLNPGM("MMU <= 'C0' (keep trying)");
            MMU2_COMMAND("C0");
          }
        }

and replace with

        #if ENABLED(PRUSA_MMU2_S_MODE)
          if ( (last_cmd == MMU_CMD_C0) && !mmu2s_triggered ) {
            can_reset = false;
            // MMU ok received but filament sensor not triggered, retrying...
            DEBUG_ECHOLNPGM("MMU => 'ok' (filament not present in gears)");
            DEBUG_ECHOLNPGM("MMU <= 'C0' (keep trying)");
            MMU2_COMMAND("C0");
          }
        #endif 

This compile but I have no way to test it.

Thank you. Just tried it and it compiled. Unfortunately DUE-MMU serial communication again started running circles around me. I will test it on Mega2560 setup once it's done with printing. Will report back if issue any arises. 👍
