char gcodeLine[25];

  for (const auto &instr : gcode)
  {
    if (instr.command == "M7" || instr.command == "M8" || instr.command == "M2" || instr.command == "G21" || instr.command == "G90" || instr.command == "F1250")
    {
      snprintf(gcodeLine, sizeof(gcodeLine), "%s", instr.command.c_str());
    }
    else
    {
      snprintf(gcodeLine, sizeof(gcodeLine), "%s X%.2f Y%.2f", instr.command.c_str(), instr.x, instr.y);
    }

    // weil Du ja auch keine leere Line pushen willst
    if (gcodeLine[0] != '\0')
    {
      gcodeQueue.push(gcodeLine);
    }
  }

So also?
